"I served a party of 15 the other day whose tab was over 350 bucks easily. They were drinking pretty much all night, buying bottles and such. After a while, another lady came to join them and asked for an empty glass. As there were multiple bottles open, this wasn't out of the ordinary.

After I handed the glass to her, I turned to talk to another table. As I was passing by again, I looked over and saw this woman bent over next to her purse, pouring something into her glass from a bottle apparently hidden in her purse.

She might've gotten away with it if she'd been smart enough to notice the rest of the vino bottles were exclusively red and hers was white."
