Questions: Health & Fitness

Let's say you go to a small gym that is a free amenity for residents of your building. There is no staff working there. It is open 8am - 10pm.

You walk in and there is one other person already there. They are working out.

The lights are on, but not all the lights. There are two light switches on the wall and there is always the option to turn on one or both switches, which is either all lights, or half the lights. In both cases, you can see the gym and equipment clearly. You can see all the numbers on the equipment. There is nothing you can't see but the light is overall a bit dimmer.

The question is: When you walk in...
Do you leave the lights as they are... ask the other person... or just turn all the lights on?

(And yep, this keeps happening that four different girls have come in and wanted all the lights on. Some ask first, some just turn them on, but none of them seem to respect the fact that we are already there, and like some people, prefer not all lights on. It feels like a hospital when they're all on. And it's not a safety issue. It's not much darker with just the one light switch on. There are mirrors on one wall and security cameras on and a F/T building staff in the lobby who keeps an eye on all camera feeds.
It doesn't happen with guys. Guys don't make any changes. They either prefer less lights on, or they adapt to the situation and whatever the other person has selected.)
