This has happened to me several times: I'm trying to use a public restroom and someone knocks on the door. I respond "someone's in here," they wait a few moments, then knock again.
Now, I don't think anything is going to come out any faster because you knock twice. It's plain rude. When I do come out, wipe that snotty look off your face. I won't start pinching anything off to appease you.
The best part- there's a friggin bathroom right over there! (Literally, a bathroom five feet away.) You don't have to use this one.
Would this bother you guys? IIN that it bothers me?

=P
I'd even come back to the bathroom and wash my hands really slowly so I could observe them in their futile knocking.
