Mediocre is an a bit of an overstatement for that pizza. It is serviceable, but the sauce they use tastes like it has sugar in it or something. My kid loves it, but I am not a fan. I don't think it costs that much more for them to cook the pizza for you in their little cafe.
Let's dont go crazy here. I prefer to eat some things with my hands is all. Pizza is one of them. I have used a knife and fork on occasion when it was needed for an extremely hard to manage pizza.
As far as the washing hands thing, I tend to do that regardless if I have eaten with my hands or not.
