One time she told me: "I don't know why, but black customers always leave $2 tips, no matter what the bill is."
I don't think it's race, just culture in the US.
And yes, it's true about black customers complaining a lot, so they can get "free" meals. After they've eaten everything on the plate.
This scenario came up several times: A family would come into Sizzler, order one steak, and one salad bar on the side. Of course, then the whole family would help themselves to the salad bar with the one plate. When the manager confronted them they would always say the same thing: "It's because I'm black, isn't it?"
The manager would say: "Nope, we have plenty of white people that do that too!"

I was a bus boy back in HS at our local Sizzler and that actually happened back then, and still goes on today. Saw it for myself. It is what it is.
