Not kids friendly

Was invited by friends for the first bday party of their daughter On 19th March. Food was good , manager, waiters were Attentive. There was live music and the guy had performed for over an hour with no one dancing. In our party were 5 kids ages 4-10 including my son. The kids went up to the small dance floor to dance and as no adults were dancing I allowed it.The guy performing stopped after the song and screamed take your children off the dance area and annouces on the mike that this area is a dance floor not your childrens playground. Considering the children were the only ones who were dancing not sure what the problem was. Was very embarrassed. Nedless to say our group left. Will never go there again!
