They allow me to pay hundreds of dollars a year to use their facilities 100 times a year (that's a very
optimistic view of my gym attendance).
They have plush little orange chairs in the women's locker room, just in case you need a place to sit and relax while you finish your Wal Mart list and try not to stare at the 70 year old Asian woman who proudly walks around without a stitch on as she gets ready.
They have not yet kicked my eldest out of their childcare center, despite his abundance of 'incident reports'.
But mostly, I love my gym because when I email them about something, it always go the owner. And usually, I have a response within hours, if not minutes. It may just be, "forwarded to such and such, sent my from blackberry", but it's a response. And I'm prone to emailing people at midnight on Saturday, figuring they'll answer on Monday. So kudos to you, Mr. Gym Owner. You rock.
