Proper Gym Etiquette

I have been in quite a few gyms, and I have come across some great people and some not so great people. Everyone goes to the gym for the same reason, to workout, so why do some people disrespect others by not clearing up after themselves and having bad 'gym etiquette'?
Here is how to be good in the gym!
- Put equipment away after you have used it - don't just leave weight plates on bars or on the floor, dumbbells on the floor or benches moves out of position. If you use equipment, then put it back for the next person to use
- Wipe equipment down - If you are having a 'sweaty session', then make sure you wipe down any equipment with your towel before moving on. Would you want to use a piece of kit that has someone else s sweat covered in t? no, so don't leave your sweat behind!
- Don't hog equipment - If your using a piece of equipment, but need to go away for a sec, then it's okay to leave your towel on it or something, but if you know you are going to be gone longer than literally a minute, then don't try and 'hog it', let someone else use it, especially during busy times! Also, don't have 5 min rest breaks in between each set if someone is waiting to use the equipment, it's not just your gym yano!
- Concentrate on yourself - Don't be a fool and mock other people or just stand and stare. You are there to workout yourself, not to laugh at others. Everyone is there for their own reasons, so make sure you stick to yours.
- Help out others - if you see someone that is struggling with weights or looks like they need a spotter, then offer to help them out. Don't just jump in straight away though,  you don't want to be known as someone that walks around asking if anyone needs help, but if you see somebody struggling, then by all means, offer to help.
- Don't pretend to be a trainer - Gym's have trainers, so you don't need to pretend to be one. You may well be 'tanked', but that doesn't mean you are able to offer your 'services' to somebody, this can make you seem arrogant and if things go bad, you are not a qualified trainer and will be liable fr damages!
- Lastly, guys - don't go round 'hitting' on every woman! - Women are there to work out too, not to be hit on by some guy she doesn't even know. I'm all for making new friends in the gym, but don't think its okay to treat it like a speed dating room!
