Hi S.,
I have taught gymnnastics and dance for 15+ years In mutlple studios. We always promised to end and start on time. I would talk to the owner of the studio it could be a scheduling conflict. Do the classes start back to back? There should be a 10-15 minute interval between each class for instructors to talk to parents. Other wise the teacher should ask the parents to e-mail or call them with any concerns regarding their child. Good luck. Remeber it is a small buisness and any feedback they gat is helpful to them.
