Fully disagree. I've had terrible service & I've had great service. While I've never completely stiffed a waiter, I have left a tip on the low-end (10-15%).

Fully disagree. I've had terrible service & I've had great service. While I've never completely stiffed a waiter, I have left a tip on the low-end (10-15%). And I've left killer tips (>50%) on some really killer service. By and large, the system seems to work pretty well. And once you know to accodate it, it's not really that hard to do the math & account for it.
