Goes back to acting professionally - you should never feel like that when you're just trying to put in place what has been agreed.
The above point in bold could be another thread altogether! I've had nightmares when staff / managers are basically working against you and the whole event. That is the one thing that has really annoyed me over the years - Some 'jobs worth' throwing his weight around for the sake of it.
There was 4 different managers over The Embankment Club years, and one in particular was so miserable and awkward, one night he was so rude to a regular record dealer there, the guy packed up and went home! I rang him the next day to apologize, but ffs, you shouldn't have to be 'picking up the pieces' after miserable management! (There's enough to think about when running an event)
