Would this item ruin a perfectly good pizza for you?

Wife and i were eating at Pizza Hut the other day. While waiting for our pizza to arrive, another pizza arrived at the table next to us. The man asked the waitress if she would bring him a bottle of ketchup(catsup). This she did. I sat amazed at the amount of ketchup this man dumped on a perfectly good pizza. He now was about to eat a ketchup pie, instead of a pizza pie. I realize people are all different, but this was ridiculous. I hate anchovies on pizza. Question: Was my opinion of this man correct, that dumping half a bottle of ketchup on a pizza was ridiculous?
