I'm male, and I often work out at around the time where the staff at my gym is cleaning the showers. They aren't doing it at a specific time, so I can't plan my way out of it.
When it's female staff cleaning, I have to wait for them to be done with the whole locker room.
When it's male staff I just have to wait for them to be done with the showers (there are only 4 showers, in a small space).
Last time there was a guy cleaning the showers thoroughly, so I went on the treadmill while I waited for him to leave the locker room. So I didn't have to walk in and out to keep checking if he was done with the showers.
But when I went in 20 minutes later it seemed like he had been done for a long time.
This is a pretty small problem, but I would still like to hear any suggestions on how to ask them: How long it will take before I can use the showers?
Because I think if I ask them like that, they'll take it as i'm trying to rush them.
