I have mixed feelings about this. I remember when you didn't wipe anything down, next thing you know people are using paper towels to wipe everything own, complaining because you're making a noise, complaining because you're banging the weights too loudly on the floor when deadlifting, complaining because you're using chalk, and complaining because you're squatting in the squat rack when they're waiting to do curls ........
No paper towels in my gym, claiming its a green gym. More like saving on costs.
Only issue I have with my new gym, is people are lazy with not putting weights back. I spent a good 5 mins yesterday tidying up weights because it annoyed me looking at them.
