My gym in the last year has lowered it's price by half and of course this has attracted all kinds of new people and at the price it's at now it also attracts the kind of people you don't want in your gym. I never really had issues at my gym until this price change brought in these annoying people with no gym manners what so ever.
The gym is a constant mess and you cannot kind dumbbells or plates that easily these days because those people don't put their weights away and they leave machines all loaded up.
But I have 2 cases lately that really pissed me off.
1) I had just moved to the Hammer Strength Incline Press machine and put my drink bottle down and bag down at the machine and loaded a couple of plates up then walked over to weight tree 3 meters away to grab 2 more plates I needed and turned around find some guy trying unload what I had put on (I had my back turned for 5 seconds max) and start yelling at him hey I'm using that and he flat out ignores me. I get back at the machine and ask what he is doing and he is like oh sorry I'm using this machine and I said no I was here first and he just walked off and I had to reload the machine.
If he actually asked me if he could work in with me I would have let him because I always let people work in with me.
2) The 2nd case all the benches were taken in the gym (3 of them had people just sitting on them curling ffs, curlers are another bad problem in my gym) so I waited a bit to see if one became free. One of curlers stood up and put his dum bells down so I was in there and asked if he was finished with the bench and he is like no and goes and grabs an ezcurl bar. I'm like ok sweet as "how many sets ya got left with the bench" and he is like "10" wtf. Then I ask if I can work in with him on the bench and he is like No and I swear I was about to smack this guy for being such an arse, he shouldn't have been curling on it in the first place. Luckily at this point another bench became free. To make thinks worse the guy only did 3 sets (not 10) of skull crushes on the bench and left the gym after that. He was some noob doing an "arms day". I haven't seen him since luckily.
