Ha, ha...I had same experience but luckily I can skirt the bad hours of 4-9pm. It has some great equipment and decent classes - that is when they're not over crowded or have too many novices interrupting the flow.
I don't mean to be unkind, but there is a compatability issue between athletic and experienced members, and grossly obese and new-to-fitness members. I aplaud the latter for trying, but it would be nice if they were less 'entitled' and a little more polite.
My time is as valuable as there's and I take offense to instructors who solely cater to the lowest common denominators and ignore inappropriate behaviors. In the long run it hurts everyone...and business too.
