Whats the profit margin on chain pizza stores?

[phreaqe]

I am one who does not mind chain pizza generally, and think the pizza snobs are super annoying. Any pizza is good pizza and sometimes you want different kinds so places like papa johns and domino's are fine. That being said Pizza Hut is the worst pizza anywhere. I have never had food where the ingredients feel so artificial and manufactured. The sausage pieces all look like they came out of a mold or something....
