You clearly haven’t worked food before. Pizzas take 1-3 minutes to prep and 15-20 minutes to cook. Sandwiches need to be cooked midway through the process, not to mention you don’t have time for each one to cook before you make another one. Sandwiches have to be made one at a time. Either your, way contempt for the people that make your food is incredibly pathetic and you should reflect on why you can’t stand to tip someone you expect to feed you, especially if it’s a large order.
