How does the food and beverage department divide the service level?

It's ok for star-rated hotels to divide waiters into eight grades, but it's a bit too much for ordinary hotels.

Rating: trainee waiter-> C-class waiter-> Class b waiter-> A-level waiter-> Junior trainer->; Intermediate trainer->; Senior trainer-> Reserve management personnel.

Promotion standard: new employees are rated as trainee waiters, and they are rated as C-class waiters after working for one month; Class C waiters are trouble-free in that month, and their attendance is not good. Those who work hard can be rated as Class B waiters. B-class waiter was rated as A-class waiter with trouble-free, poor attendance, hard work, independent ordering and error-free. A-class waiter, trouble-free, poor attendance, hard work and strong promotion ability. The average unit price of ordering customers exceeds 80 yuan/person (the standard is self-determined). ............
