"Ms. Important demanded to speak to our manager, so I sent our manager over and attended to my many, many tables, refilling coffees and bringing out breakfast orders. My manager came up to me and said, 'I'll prep her the salad, just punch it in.' Fine, I had already put their breakfast orders in anyway, so I brought out their food, topped up their coffees quickly, and dropped their split checks. They paid and left, and I came back to help the busboy clear the table (again, we were completely slammed). Of course, no one left a tip.
"I was irritated but not surprised. However, sweet karma appeared in the form of Ms. Important's office ID hidden under some crumpled napkins. I told the busboy to keep quiet and not say anything if she came back, and instead to send her my way.
"10 minutes later, in came Ms. Important. She made a beeline for the table she had been sitting at, only to see it occupied with another four-top. She accosted the busboy cleaning a nearby table, and he pointed to me. I was walking over to pour refills of coffee nearby, and she stood in my way, demanding to know what had happened to her office building ID. If she'd been nice about it, even after stiffing me, I would've given it back to her.
