Generally, the catering sales manager does nothing, the waiter serves in the meal, and the sales manager does not participate in direct service. Generally, the treatment of five-star hotels is not too bad. Responsibilities of sales manager: maintain old customers and develop new customers. Sometimes guests will toast when they come to dinner, so they should have a certain amount of alcohol. Many sales managers earn their performance by selling their bodies, just decent "chickens"! Five-star is no exception, of course, there are some individuals who don't, and of course the performance will not be good!
