Pizza Buffet Crapflooding is the practice of buffet employees filling the pizza buffet with unpopular pizza, so people will eat less.
I walk into the Pizza Buffet ready for a serious pizza munching fest. I go up to get my first plate. Everything looks good, a nice selection of pizza, not a lot of crappy pizzas.
The place got busy while I was eating my first plate. When I went back to get my second plate the buffet was empty. When the pizza buffet workers see an empty buffet they start crapflooding. A minute later they put out the first crappy pizza (it was jalapeno). None of the ten people standing at the buffet waiting even approached it. Two minutes later they added a mushroom pizza. No one touched that either. A couple minutes later they added both a black olive, and a green pepper pizza. One man took a single slice of this and went and sat down. The next pizza to come out was the ever so popular Green Pepper, Onion, and Black Olive combination. (Which was still untouched an hour later when I left).
Finally they put out a cheese pizza. Half the people in the restaurant tried to get a slice. It was gone in seconds. Only when the place began to empty out did they start making popular pizzas again. The sausage, pepperoni, and ham pizzas finally began to make their way onto the buffet.
Until they got busy again, then it was nothing but peppers and olives.
