I leave our mousekeeping envelope on the bathroom vanity.
To a point that is true, and if it's in an envelope also, BUT, if they happen to just straighten up, and not really LOOK at the envelope, then they may miss it, or if it's not clearly marked as 'theirs' if they WOULD take it and werent supposed to..... Boy oh boy.. now they are guilty of theft.. Not a good thingif they cant find it, they probably didnt do a very good job cleaning the room and dont deserve it.
I have a silly question and feel silly for asking. But how much do you tip MouseKeeping?
