On the subject of Pizza, we have this place here called Girdis (don't ask how to spell it ok" anyways they are this old style brick oven pizzaria and will litterally put any topping you want on it, they make the best pizzas ever and will put any topping you can think of. They don't do delivery though, but they are all you can eat also.
So a side note on the Pizza Hut, I find it funny that they are just now gettign around to advertising their pastas, which they have had forever, and now people are like "oh wow Pizza Hut now sells Pasta" when they always have.
On the Cheeseburger Pizza, yeah it was grose and didn't last long.
Now onto the tip subject, tipping is a must anyone who doesn't leave a tip is a cruel heartless bastard! you try working for LESS THAN minimum wage and then get stiffed on a tip you worked your ass off to get. Seriously the tipped employees get paid, after taxes, like $3.00 an hour, they LIVE on their tips.
Even if the guy was a jerk, you have to think outside of why he was a jerk and figure hey his life sucks ok he is working for table scraps and sometimes payday rolls around, the power bill is due and he put everything he had into the gas tank.
