I frequently buy myself breakfast on the way to work - a quick biscuit at one of the five or six places I pass in the morning is quick, inexpensive, and a nice treat to start my morning (I am SO not a morning person). I went through Hardee's this morning, and when I got to the window, I was told that the lady in front of me had paid for my meal. This was, of course, a very kind gesture, and normally I would offer to pay for the person behind me - but I was the last one in the line, and it being still quite early, there was no telling when someone else would come through.
I was left with a dilemma, and although I simply thanked the person at the window and moved on, I wasn't quite sure what I should have done. Did I do the right thing?
