For those members of our audience who are not actually from Riverside (there seem to be a few from time to time)...We currently only have one working set of showers, so the women use is from X:15 to X:45, and men use it from X:45 to (X+1):15, for all values of X between 0 and 23. For those who couldn't understand this explanation, sorry, I went to MIT, I am not so good with words and stuff.
