A few weeks ago when I was returning from the university library and had stopped through a tasty campus pizza place for a specialty slice, there's a (fattish) (sloppily bearded) (South Asian-American) guy ahead of me in line, and as he picks out 4 slices to go, he chooses the last BBQ meats one, and that was the very one that I had seen before but never tried but was now in the mood for today.
So, as I get up to the counter, I ask the (chunky) (affable) (face-pierced) (black) countergirl if they have any more slices of the BBQ meats specialty pizza variety, and she turns around towards a rack of full new pizzas and checks for me and then turns back and says no, and then that other customer who had bought the very last slice butts in and says that I can have it, and he'll get something else!
Just very nice of him and totally not necessary, though of course I said yes!
I thanked him then, and again on the way out, too, telling him the last time that that was very unexpected and just a very nice thing to do for another person.
He also bought some empanadas out of the empanada warmer by the cash register, so I asked him for recommendations, since I've been trying to try those lately.
He strongly recommended the sriracha chicken kind, which are his girlfriend's favorite, he said.
