Few debates have become as contentious as this one. Ask any server, and they'll more likely than not want to smack you. Ask the patron who just tacked an extra $20 onto their dinner tab after a nice evening out, and they'll probably breathe out a desperate, "Oh, please!" With $15 cocktails and far-less-than-minimum-wage hourly rates, it's easy to sympathize with both sides. But it's more complicated than just tip or no tip.
