I belong to a local (v basic, no frills) gym.
Was there early this morning, did my bit on the treadmill, came out, went into changing room, took off my gym kit and went into the shower.
Came back into the changing room and there was a bloke (not one of the gym staff) doing some sort of maintenance in a cupboard on one side of the changing room (not quite sure what, looked like it contained electrical equipment).
I obviously wasn’t going to get dressed in front of him, so took my clothes into the loos (off the changing room) and got dressed in there, which wasn't ideal.
There were no staff around when I left to mention it to (there is no reception desk or anything) was thinking of complaining by email - would you? I appreciate it may have been essential work, but it just seemed a bit inappropriate for him to be in there when clearly there was someone using the changing room (all my clothes, bag etc were there).
