Golly. All that client drama could have been avoided had he excused himself for a moment and told them to leave out of earshot. I would have been so (potentially) embarrassed no way would I have involved the client.

There are kids at that age are straight up stupid. Two girls, that age, away from parents, all sorts of silly things can be thought up in their heads.

But that does not excuse them.

I think it sucks that you could not have told them to leave and take flight immediately. Personally I would have told them to go away and look for a flight at a decent hour. Learning to try to tamper Anger and anxiety is a life long lesson

Its unfortunate but you might be NC forever from them bc it seems to be the thing now-days.
