Question:
What's wrong with brushing your teeth in the shower?
It's certainly not as bad as pissing in the shower, which I don't usually do, but I'm not gonna get out of the shower just to take a piss unless there's someone in there with me, in which case it wouldn't be very polite.
Answers:
Nothing. Lots of people do it to save time. The water goes the same place as from the sink.
