Personally I love my pizza with extra sauce especially when it's one of my favorites, however some time back I ordered from Pizza Hut for the work place and they informed me they charged extra, normally I order from Domino's if I order chain, but co workers had a preference.
So it got me thinking is charging more for Pizza sauce normal.
Should Extra Sauce on a pizza be considered an extra $$ topping?
Also as a follow up:
What are some of your off the typical menu toppings you like added to your Pizza?
