"I was recently at a gas station where the pumps were both full service and self-serve. I accidentally went to the self-service bay and sat, waiting for service, silly enough. The gas attendant came running out and pumped my gas anyways. It was nice of him to do that, and so I tipped him a few extra bucks."

"Working in retail, I have seen all types of customer service nightmares. There is a store in the mall where I work that I like to go to when I am on a break. I went to look for a particular shirt that I saw in their online store, but they did not have my size. The sales person ordered it for me from another location and had it waiting for me the next time I went back. I didn't ask for that service, but it was cool that she took the initiative. Of course, I bought the shirt. I brought her a Starbucks latte later as a thank-you gesture."
