b/g I workout at one of those places that is accessible to their members 24/7. There are hours when it is staffed, but most of the time when I go it is outside those hours. We have key fobs we can use to get into the place during the non-staffed hours. If you let someone in who doesn't have a fob, you can be charged $50.
This morning while I was working out on a machine by the front window someone was trying to get in by ringing the bell, and then she asked me through the window to let her in. I refused ($50 is a really good determent). She gave me a cat-butt face and said something; I think from reading her lips, it was that she forgot her keys or she'd left her keys in the gym. I don't know, but either way, I wasn't going to let her in. Eventually, another member let her in, but she was obviously not happy with me based on the looks I got through the window. The rules are clear, they are posted by the door, and also, honestly, I was in the middle of my workout; I would stop for an emergency, this wasn't one.
