#10: Gym Etiquette
There are certain spaces in society where people have to act according to certain codes. And whilst this might sound restrictive and strange, there are some places that might crumble without such systems in place. When a place has communal aspects to it, everyone needs to work towards keeping it a nice space.
If you frequent a gym, then you know that there is nothing more frustrating than seeing things like this when you walk in. It is a basic courtesy to put things back once you have used them, especially at a communal gym. Not only is it annoying to have to clean up after others, but it can also be dangerous for some people to have to put weights away – especially if they are too heavy for them.
