It was just so unexpected for these two high-maintenance, gossipy ladies to give me a twenty dollar bill as a tip! They'd been polite enough, but were totally absorbed in their conversation and had camped out for a while (though I had empty tables so that was fine). I was expecting ten or fifteen percent, but when I broke their hundred dollar bill one of them handed me a twenty. Their bill was about $30, I think.
Totally made my day, of course! So I asked if I could hug her, and I did. Guess that's one of the perks of being a short, chubby young(ish) girl--people don't think it's creepy if I do that!
