Pizza Hut

I've been to this Pizza hut many times. But always have had bad service. Once, a group of my friends all went in to eat their buffet. 2 of them did not eat, and it was apparent because there was no plate in front of them. but because they "sat down" they automnatically were put into the bill. Pizza hut called the police on us because we threatened not to pay. In the end, we paid but left no tip whatsoever. stay away if possible.
