Yep. Probably a group of people training together and using random equipment to hold all their shit while they train elsewhere or even nearby.
I see this every fukking day at my gym and I think it's ignorant.
There's a group of 4-6 people that do conditioning work with a trainer every morning at 6am and they put their phones, water bottles, towels etc. all over other equipment.
Also seen a member of my previous gym come in every morning and put his keys and newspaper on a bench then go train elsewhere. It's stupid. Keep your shit with you or leave it in your locker.
I just move the shit, they will jump out of the wood work, when they see someone touching it....then if they want to an ass about it, the rage comes out. If not then all is good....
