waiters是什么意思？

But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one.

One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you.

Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn't believe the job they did had any impact on the tips they received.
