You deserve to have the soup spilled on you. My blood pressure just skyrocketed when I read that you never tip. In most restaurants in the US if you don't tip the waiter not only do they not get compensated for working for you, they wind up having to pay to wait on you. Servers are required to tip out 3-4% of their sales to bar/bus/host staff. They don't get to deduct your sales because you were a (BLEEP).
