I see a short article about a few dinner parties this author attended wherein the owners were keeping the tip. Am I missing the real data here? Is the real story somewhere else? That's a far cry from "this happens _all_ the time."

Weird how the proof that owners are pocketing credit card tips is a story about someone stealing cash from the tip jar.

It has been years since I read her series of articles on the topic of tipping, although I remember it being influential at the time. It's possible I linked to the wrong thing, but in my defense I didn't realize that my post would be required to rise to the level of mathematical proof. Ahem.
