Family Pizza

I went to ask family pizza about the GF pizza and they insisted that if they cooked the GF pizza in the regular oven there was no chance of cross contamination?! The waitress was actually rude about the subject when I did not agree with her. I could never go there, even if the did change their way of cooking the GF pizza the avoid cross contamination with a wait staff that is more worried about being right than listening to a customer. If i could give negative stars I would.
