I'm not surprised the owner was a jerk (so many of those stories - a lot of fragile egos with this crowd
), but to have the girls all turn on your DD just breaks my heart.
I've seen some ugly gym switches in person. The 'stories' owners and coaches will tell remaining teammates about you, your family, your DD or DS... just twisted and sad. You could have been the most polite, careful, supportive parent who tried everything to work with coaches and resolve any issues. It won't matter if you volunteered 4 extra shifts at the home meet, spent your own money above and beyond to donate extra cases of gatorade, drove through a snowstorm to pick up the pizzas for the team party, and baked each coach homemade cookies attached to a generous gift card each winter. In the end, you will be talked about as 'crazy' and 'unreasonable' and your child lazy, untalented, and unappreciative. Yes, it happens. Not always, but it can come out of nowhere from people you thought until that point were rational and caring human beings.
It's all about ego, and leaving a gym insults the egos.
