Dear Tumblebug,
I know what this feels like. I would tell her that you need
to set up an appointment after hours to speak with me. I can not
speak with you now.
If that does not work I would have the owner speak with the
mom. I would have the owner go over all the rules of this gym.
I would also have the owner tell the mom why she can't speak
with you when classes need to be started which is practially com-mon sense and if she can't follow these simple rules she and her daughter can leave.
I hope I helped you out a little.

Love, Peace, and Pointe Those Toes,
missdancediva
