That was unexpected!

I was standing in line to get a sandwich between classes today.  The gentleman ahead of me turned to me and asked what I was having.  At the cashier's encouragement ("Are you gonna miss a golden opportunity?"), I let this total stranger buy my lunch.  I haven't any idea who he was; he might have been a professor, but who could tell.  (I've been mistaken for faculty once or twice, just because I'm so much older than the overwhelming majority of the student body.)  The cashier didn't seem too surprised, which leads me to think he's done this at least a few times before.

What a nice little surprise on a chilly, overcast day.  I also found a $5 bill earlier today; this seems to be my lucky day!
