When working in a restaurant, how does new wait staff learn the policies if they don't start out as host?

some restaurants don't hire the new wait staff as a host they just put them right up to server, but isn't the hostess the position that knows all the policies on guest services, restaurants rules and procedures etc ?

There should be at least one day with some form of training, at least a few minutes of explanation. If nobody offers information, grab somebody who's been there a while and seen a lot of newbies. They'll know what to say.

Ok, my aunt and unkle own a reastraunt and i know all about this stuff:

host and wait staff are sorta tthe same thing. before they hire you, you have to fil out and application, and read about all the procedures and stuff you have to do. if your good enought, they hire you. Other people that work there are suppose to help you if you need anything
