...uh...usual time. Have to walk twice as far to a colder, darker, older bathroom. And guess where they go to clean next? "Knock knock....house keeping!"

Then you have to shout back that you're in there. And then they stand outside the door and wait for you to finish. But this bathroom has no outer door so she gets to hear all your noises and then you have to walk right past her on your way out. And if you happen to take a while in there it's even more awkward.
