When ever you go to a restaurant you just shouldn’t speak to the waiter. Its far too dangerous of a game to call them out and have them in total control of the food you’re about to eat. Unless its to order your food just don’t say a thing. I don’t even like being nice and chit chatting with them because if they’re nice back i feel obligated to tip more even though I’m poor. And you most certainly shouldn’t say anything bad about the waiter right to his face. If anything complain to the boss after when foods already digesting and you’ve survived. But to complain to the waiter and pissing him off before you get your food? You’re asking for a massive bowl of blazing hot soup to the face.
