People say this, but what is better service?

It's not like you get better or more food, or get the food faster since all that depends on the kitchen that isn't getting tipped directly.

It's pretty much them coming to your table to take your order. I'd much rather have a free burger or drink (the equivalent of what I could get instead of tipping) with the slow service than get my water refilled every 5 minutes.
