Life was so much simpler back in the 70s - I recall as a student at UWO going to the Mustang football games (when students were still allowed to drink in the stands and the stadium was packed) - girls would use the stalls in guy's washroom since their lineup was huge.  As guys we didn't care much as there was just a long trough vs individual urinals to stand at (and with my "bashful bladder" it was a waste of time anyway) Mind you liberal use of alcohol broke down a lot of social concerns.
