You will find CPs at Full Service. But they do not work as servers. They work in the front as a hostess. That is what I did. I worked at the Hollywood Brown Derby as a hostess. I signed in guests, seated them, occasionally assigned tables and bussed tables and assisted the servers during extrememly busy times.
The job duties vary by restaurant. At Hollywood and Vine where I helped out a few times the hostesses did all I said above and ran silverware, folded napkins, cleaned the buffet and other duties. It really depends on the restaurant.
