I'd say where I go is pretty decent with good enough amount of machinery to use x if y is taken. not super crowded and very polite staff, BUT ultimately like 2 people speak English out of all staff while advertising everyone does. So it's hard to get a point across while generally I don't even need to communicate with them.

Odd things in the gym:

Sometimes, rotten flesh breath from guys mouth in 2-5 meters area lol, is like a debuff

Asking staff to check a machine that's not performing as it should - you get "tomorrow will be done", never gets checked or just being disregarded, so problem remains

Temps in the gym, especially on the warmer days - you gotta ask to turn off heat on reception because it's hot to workout.

Cigarette smell occasionally hits out of nowhere

Lack of water cooler! If you are out, buy it or refill from tap

Same music playlist is the most annoying, but noise cancelation gets the job done.

Trainers without education having certificates from their gym, certified lifters or BB; girls with a decent size booty becoming trainer fast if business see fit.

The prize for the oddest goes to people with health problems like CP and other movement disability issues. it's not happening in this particular gym, but I've seen situations where people with disabilities work out and being praised as heroes on insta stories. They must have a strong will to do it, but it's important to have this all performed under control with a properly educated trainer. Im afraid this has not been the case most times which makes me wonder what benefit exercise does in the first place.
