A "quick" pizza in that heat means a sure "quick" death for a kitten in a hot van.
I don't know if you all have Chuck E. Cheese where you live, but there is no such thing as a "quick" pizza there! Especially with a bunch of kids. It is full of arcades, toys and singing life size puppets. They give you a bunch of free tokens when you buy the pizza. There's no way you take a bunch of kids in there, eat and run.
