Re: general question
I see what you're getting at but I can't quite imagine what this member of staff is going to check for in the cloakroom. When he/she walks into the cloakroom it won't be possible to tell of anything has already gone missing/been lost and, unless you expect him/her to stay in the cloakroom for the rest of the evening, it won't be possible to check that nothing gets lost before the end of the party.
