Devil (or customer satisfaction) is in the details

I am in Chicago for two weeks. I happen to like this particular coffee shop (Bean) at the lobby of the building i am staying at. This morning the barista thanked me by name when i picked up the coffee. I was curious how she knew my namesince I am not from Chicago and I have been at the shop only once before. Turns out that the guy who took my order read my name from my credit card and passed it to the barista. Not a big deal but a great little habit to have if you are in the service industry :)
