As a parent who sits in the viewing area and watches I was recently subjected to 2.5 HOURS of a rant

from a parent who is not happy w/ our gym. Is our gym perfect? No. I doubt there is a perfect gym.
She complained about how may skills her daughter has "lost" since coming to this gym.

Ok, why are you still here? Go back to "X" gym - oh - can't go back there, she will be too embarrassed by the amount of skills she has lost

This is the only girl in the gym I am aware of not gaining skills. She has been passed by several girls.
Anyway - not enough room here for the whole thing. Trust me the 2.5 hours is NOT an exaggeration (another parent came in about an hour into it).
I think that different programs work for different people. I think that most people know that and will take this w/ a grain of salt. Especially if they know that this person whines every time they walk in the door.
I understand the whole Customer is always right thing however, if it is undermining your business and they are that unhappy, you should have the right to say "perhaps my program is not for you"
