Massage Envy

My husband and I have been going to the same massage envy for about 7 months now. We get a couples massage each time and due to circumstances we have to take our children age 12 and 6. They have never been a bother to anyone and wait in the waiting groom. Last night we went in and got our massages and as soon as we went back the manager went out and started yelling at our children for having any bit of volume in their phone. She was very unprofessional had a very bad attitude. She was completely rude to us when we got out as our kids were minding their own business and not bothering anyone well because there would have to be someone in there for there for them to bother. I could understand if they were jumping around and being out of control but they never are they always sit and play on their phones very quietly.
