I don't know if I've been stuttering or if I spoke in a foreign language but we have had a NO CHILDREN policy for 3 years. Apparently I have to let people know over the phone.... ummmm.... not EVERYONE has children and I don't know why it's my responsibility to have to tell you?! Simply my clients come to get their nails done to relax and not having to worry with children screaming or running up and down the shop whether it's their children or others. Let's be honest, it's really boring for them and if you get those children that touches everything it's a potential hazard and they can hurt themselves as well as others.
The rules are rules and it's placed in the salon for a reason whether you agree or disagree.
