A tip I can give is that Cast Members are actually human beings, with full human qualities, which entitles them to make mistakes. If one does make a mistake in front of you, tell them it's okay, and smile. It will make it a lot easier for them, because as a Cast Member, we HATE going up to a guest and telling them what they don't want to hear.
Some examples that we envision in our head what will happen:
CM - "Sir I'm sorry I forgot your fries, I'll get them right now."
GUEST - "::long sigh::OH GREAT! THIS GUY FORGOT THE FRIES!! YOU BETTER GIVE ME MY MONEY BACK FOR IT!!!"
CM - "Sir I'm sorry I can't do that, I can go get a manager if you'd like."
GUEST - "No whatever just hurry up."
Or don't get mad at us when we are doing our jobs and looking out for your safety and best interests.
CM - "Welcome to Epcot everyone, for your safety, please walk in front of the parked cars for your safety, and also so you don't hold up traffic."
GUEST - "You know, you charge us $14 to park and make us park a %#%$^% mile away, don't tell us where to walk."
CM - "Okay"
::traffic holds up due to guests walking in front of incoming traffic::
GUEST - "You know if you parked us up front here we wouldn't have to walk in front of the parked cars."
CM - Just doing my job sir.
