BaddJack's comment in another thread reminded me of a similar one a few months back. My wife and I were in a local fast food place for lunch, and a very nicely shaped girl in a mini-skirt and tank top was in front of us digging through her purse for the last part of what she owed. After a few minutes of watching her fruitlessly searching, I pulled out the leftovers I had and gave her the two she needed. She looked embarrassed, but took them with a "thank you".
Before I could even open my mouth for a response, my wife pipes up with, "Don't worry about it, he likes giving singles to pretty girls." The poor girl turned as red as anyone I've ever seen, and the counter staff was disabled for a few minutes.
My wife apologized to her; she'd meant it as a dig against me and wasn't trying to embarrass her.
