Unfortunatly, we did talk to the manager. He was the one who made the pizza. My husband called him, and kind of got the impression that the guy did it on purpose. There shouldn't have been any meat on the pizza, anyway, since it was a vegetarian pizza. The lack of cheese was a special order; the lack of meat should've been standard.
I did fire off a nasty complaint to the corporate headquarters. I gave them the name of the manager, quoted him, and told which store he manages. I normally would never say this, but I hope he gets fired. If it was intentional, then he's a sick *******. If it was unintentional, then his kitchen is so disorganized and messy that it is undoubtedly breaking the health code. There wasn't enough meat for someone to have made a mistake and made a meat pizza, so it was either contamination of the vegetables (unsanitary), or intentional. We have never had a problem with meat on the pizza before, and we've ordered from this store a few times.
GRRRRR... Sorry, I am still really mad.
