Yes and these people are the bane of the gym experience.
There's this one old fat stubby bald guy that walks in with his gym bag and wear the same exact clothes everytime as if that's the only pair of shirt and shorts he can afford. I never see him on the work out floor for obvious reasons. On multiple occasions, I come out of the shower and I see him sitting in the ONE place of all the locker area that has direct view of the showers. Of course I had to walk towards him because that's the only way to get to he locker room. It's obvious wheat he's doing while pretending to play on his phone. A few other times when I'm in shower, when he does his "pre-swim shower" he chooses the stall diagonally opposite mine when 7 other stalls are empty and I notice him looking at me. Thankfully there are curtains and I pretend he doesn't exist.
Another old fat guy like to loiter the shower and sauna. One time I chose the shower furthest away from the entrance and it practically empty, I see him walk up to my curtain and stood there for a second to look at me and then leaves. I come out of the shower and of course he's sitting in the same spot the first fat guy likes to sit and gets a view of me walking out of the shower into the lover room (in my underwear of course). Another time, I see him in the sauna. From the sauna you can see who goes to shower. When a few guys walks by to the shower area, he goes out to "shower". When I see those guys walk back to the locker, this far guy comes back into the sauna. I never see him on the floor or cardio machines either.
Then there were these 2 scrawny gay kids. They appeared out of nowhere, work out at my gym for a few months, and then disappeared. If you go to LA Fitness, you know how the shower stalls are set up. It's very obviously these two were purposely doing everything they can to peep at naked men. They move from one shower to another to get a better view of the guys that just came in and they do so without discreet. One time they purposely came to the shower stalls directly diagonally to me and when I pull my curtains just enough to grab my towel, they quickly poke their heads out of the shower to try to get a better view through the gap. WTF
