My most recent LinkedIn post praised the merits of “intelligent acts of kindness”—common-sense, low-cost gestures that really make a person’s day. These efforts are “intelligent” for businesses because they are thoughtful, practical, appropriate—and sustainable. A case in point is Elisabeth Hendrian, who wrote in to my post. She used to wait tables at a restaurant and would always carry a stain-remover pen—just in case. “Whenever there was a spill or accident, guests were always relieved that I could help them,” she wrote. “My coworkers noticed and started carrying them too. Customers always loved it.”

At the end of my post, I invited readers to share moments when companies exceeded their expectations and made them smile. Here are some of my favorite reactions: (some are edited slightly for brevity):

Melissa Gladden: I once visited a grocery store with a screaming infant just after shots and was at my wit's end. The pharmacist pulled Tylenol from the shelf right then and opened it so we could get it started ASAP. He then made recommendations for the other issues my son was having and got them for me. Finally, ready to check out, I realized I didn't have my wallet. The pharmacist paid for my items and sent me on my way. My husband paid the pharmacist later in the day. In a time of personal crisis, this pharmacist saved the day! My son is now 11 and this is why I've been a faithful Safeway customer since that day.

Yudha Pratama: Meade Lexus of Lakeside, Michigan, always fill up the gas tank and washes my car whenever I have it serviced there. Last year, when using one of their loaners, I was stuck in bad weather and had to drive the loaner home. The dealer arranged to send my car back the next day to swap it with the loaner—almost 100 miles one way. I don't know if this is a standard operating procedure of all Lexus dealerships, but we love to have our car serviced there.

Anna Fedyshyn: I stayed at Christopher’s by the Bay in Provincetown a few years ago. My friends and I got off the ferry and it was pouring with rain, so we stopped in a doorway and I called to ask for directions. As we started walking toward the B&B, a man approached us with two big golf umbrellas, and asked if I was Anna. I said I was, and he said he was the owner of the B&B. He had come to meet us so we wouldn’t get wet and wouldn’t get lost. When we got to our destination, he suggested we go straight to our rooms and freshened up and “we can take care of check-in tomorrow.” I have never forgotten this act of kindness and have told many of my friends about this remarkable B&B.

Michelle Bermudez: I'm an avid online shopper and one of my favorite sites is Zappos.com. One time, I returned an item I no longer wanted, but it was lost in shipping and I wasn’t refunded because of the mishap. I had called a customer service rep at Zappos and was already having a stressful day. The rep fixed my return super quickly, set up my refund and let me vent for about five minutes. A week or two later, I got a card in the mail from the customer service rep with a handwritten note: "Hope you are having a better day!"

Rory J. O'Donnell: On a family trip to Disney World, my wife purchased handmade bracelets for the kids (and one for herself) at an airport kiosk. After checking in at the Disney resort, we noticed that my daughter’s bracelet had fallen off her wrist, and we did not know where. As we were searching around the check-in desk and the lobby with a disappointed little girl in tow, a Disney employee asked what happened. After we explained, she checked the lost and found, but to no avail. So, she brought us to the gift shop and let my 7-year-old daughter pick out a replacement bracelet at no charge. Between the hotel stay, park passes and food, we spent $5,500-$6,000 on that vacation. The bracelet sold for $8. Talk about a customer experience that contains all of the elements of customer delight and loyalty; the employee was empowered, it was in line with what Disney sells—happiness—and all for a few bucks.

Michael Belanger: Early in 2012, I had to catch a flight back to Quebec for my grandfather's funeral. I was bounced from my connection in Toronto and was stuck overnight with no family or friends to rely on. Thankfully, there is a Sheraton hotel steps from the terminal—my girlfriend back at home had taken care of the arrangements for the room by the time I arrived. The first words out of the agent's mouth at the desk were: "I am sorry to hear of your loss, Mr. Belanger." Those words were magic to me at the precise moment I needed them most. That agent took care of a no-cost upgrade to a larger suite with a larger bed, took care of scheduling a wake-up call, took care of my luggage both in and out, and personally escorted me to the terminal and ensured I cleared security despite his shift being over six hours prior. I stay exclusively at Sheraton when I travel from that day forward.

Kim McDougall: I was shopping at Costco when I was six-months pregnant and had my other two young children with me. My cart was overflowing when I was finished, and I was trying to dress my children for the winter weather outside. The grocery packer offered to get me a second cart and, when I must have looked bewildered, calmly mentioned that she would push the second cart out for me. We left the store together and she then suggested that I take my girls to my vehicle, bring it around and that she would help load my groceries. I was completely blown away by her kindness and told her so.

Stewart Hayes: I recently discovered two paper leaf bags on my front porch from a local real estate agent. Didn't ask for them. Don't know who they are. But as the fall rolls in, leaves abound and I needed the bags. I now do not need to get some at the store. Great experience! But, here's the really neat part: For the very cheap cost of those bags, now lined up and down my street are hundreds of leave bags, sporting the logo of this local real estate agent. Talk about cheap, targeted and expansive branding.

Thank you for your great comments on my last post. They truly made my day! And here’s a great story by my colleague Rob Markey about a time that JetBlue wowed him with its customer service during a storm.
