This was the situation in one of the earlier (and very funny) episodes of The Simpsons. Homer is ejected from the Frying Dutchman seafood restaurant because he’s eating them out of business. It winds up with Homer taking Sea Captain to court for faulty advertising.
In the past I’ve heard of Chinese all you can eat buffets complain about how American men can eat like, well, like Homer Simpson even though that is not how they said it.

One of the classic episodes.
In my 20’s (way back when) I went to KFC with an older co-worker, because of an all you can eat. He ate 11 pieces of fried chicken, potatos, all the sides, it was repulsive.
