Not realistic, how can a waiter carry 6 different pizzas with one hand.
Jokes aside. A pretty good game, but needs food on screen to feel like you are in a restaurant. Also, the tutorial said that the scouts can order only up to 3 items and I ordered 6 pizzas in Gordon Ramsay mode. And, how do the milkshakes work? Only managed to get 1 in 2 runs, don't know if the trigger is bugged or something.
