It happens in other places, although I've never seen something called a "leisure center". But true leisure has been rather eroded by the puritans. You have to work at work... and when you're not working you have to work to have fun and keep in shape!

I'd much rather play to work and play to have fun and keep in shape... and have plenty of downtime to recover from the play, and to daydream and to do that classic true leisure activity: nothing. (Too much of nothing gets rather boring though.)

I wouldn't exactly classify a bit of a dance as "leisure" either... but that's the good thing about true leisure. It's what you want it to be.
