Rebels

The two of them headed for the shower area. 

They entered first went through the locker rooms before entering the showers. They were both on the same route, to enter the showers you first have to enter the locker rooms the locker rooms are simple. There are several cubicles with a door where when you finished changing you could go into one to put on your clothes. 

If you are not shy, you could also change outside, as there were benches between the cubicles where most people went to change. Privacy is something that everyone appreciates and this detail of changing separately without anyone seeing your private parts is something that many appreciate. Others have no shame and can change in front of everyone's eyes.
