10% is in fact, not a good tip, despite your misplaced morals. You think by stiffing servers that restaurants will care? Do you honestly think that will make a difference, or are you just cheap? Build the cost of a tip into what you expect to pay for a meal out or don't eat out. Tip culture sucks but it's the standard and you don't have to like the standard but fix it at the ballot box, not at the dinner table.
