That she working here on Monday is fixed? --"That she works here on Monday is fixed?" This sounds a little strange because fixed could imply that it is certain, or that it has now been decided when previously it had not been decided.

You could also use words that mean either of those things; for example, "definite" means "certain" and would work as well.

Pardon me, "greeter" akin to "concierge or receptionist". "hook the greeter", Sorry.

It sounds like you a very good in restaurants. It is sad that your boss does not understand your ways. I see you must agree when you don't want to. I hope you can stay there a long time because I believe things will gradually improve for you. An umbrella bin is often called a rack or valet. People often use a coat rack for everything that needs to be held during the meal. In England and Canada "Valet" is pronounced "Val- lett". In America it is mis-pronounced "Val-lae" yet Americans insist they are correct so it is best to say "Val-lae". It may also be wise to be specific and say "May I hang your umbrella on the coat valet?" because your boss may think you want to hook the greater like in the old vaudville shows! (XD)
