Who remembers the dance hall era

My daughter has just started going to the odd disco. one day I asked her did she get any dances. She had no idea what I was talking about and laughed about it for a week after I explained.
It just goes to show how far behind the times I am.
Bring back the dance halls I say where the lad would come over and ask you to dance.
But not so good for the lad when he would get refused in front of everybody
