PORTLAND, Ore. (AP) — A small but growing number of restaurants are doing away with the tipping model that has long been the norm in the United States.

It's an effort to even disparate pay among restaurant staff and a means to cope with rising minimum wages and other industry changes. Some restaurant owners say tipping is a flawed system.
But restaurants that have eliminated the entrenched practice have seen mixed results — and some ended up abandoning the experiment.
One restaurant owner in Portland raised prices about 20 percent to compensate, and says everyone now shares in the success of a busy night. But another said he realized it was "a terrible idea" after watching customer after customer push cash toward his staff and them having to refuse it.
