Do you tip? If so, how much? Does it vary if it's No.1 or No. 2?
Do you partake of all their goodies (e.g. mouthwash, cologne, personal toiletries, etc.)?
Do you *ever* feel comfortable with them just sort of standing there? Even with a stall separating the two of you? Like, are you OK passing gas like the Hindenburg just popped?
Personally, I don't like them.
I know why they're there, at least for certain restaurants/venues it is a necessity. But still ...
