Okay, so the short answer is, "yes", you do take pictures of food before pranks (and not before pranks...or rather, "before" "not pranks"). Quite a bit, it seems. You should submit some of those pictures back to the restaurants, some of them look quite good. (Not the pepper flakes picture, though. I doubt the restaurant would appreciate that.) It's quite common to call individual pizzas "pies". I think most of the chains do it internally.
