I went to a Jr. High to work a girls game, and asked where we were to dress. The coaches huddled, then decided to put us in the girls PE locker room, "since school is out and nobody will go in there." It just so happened to be parent teacher conference day, and just as I was about to begin stripping down, in walks some 12 yo girl and her mother.
I went and changed in the restroom.
After the game, they moved us into the coaches office in the boys locker room so we could have a shower to use. I'm just about to start stripping down to take a shower, when somebody walks into the boys locker room and hollers for everybody to leave because the visiting team will be changing in there.
The good news is that the shower at home was completely unoccupied and there was plenty of hot water.
