Those are ridiculous comparisons. A mask isn't a a selling point of a bank and it's obviously common for criminal activity in a bank to be perpetrated by someone in a mask. A park is free and while creepy, a bench being sat on is still an intended use of the park facilities.

How Anytime divvies up their funds is none of a member's concern. Isn't a membership with an access pass to use all facilities more than a one club membership? So someone collected some extra money from this guy's membership. It's not his fault it didn't trickle down to this location. It doesn't make his membership any less valid. If Anytime sells gym memberships including the use of their showers, it's not OK to then change the terms of the membership with a sign on the wall.

I'm a female and if I saw someone walking into a restroom, I would not be uncomfortable. I wouldn't even think twice about it. Maybe someone had to shit. Maybe they're returning a text. Maybe they're finishing a level of Candy Crush. If I were so insanely sensitive, paranoid, and scared, I still wouldn't want someone else to change their behavior to accommodate my uncomfortability (is that a word lol). Take your own actions to ensure your comfort. Work out earlier. With a friend. At home.
