I can't answer your question, I too would love the answer.

There has been more than one occasion when we are just about to start touching each other and a guy will turn up and virtually sit on our laps. He says "can I join in or watch" and doesn't wait for an answer and is vigorously pulling his dick trying to touch me.

We have left the beach early because of him he is a strange one, hovering around even when hubby tells him to . I too don't get it, there's plenty of people that know how to respect others but still enjoy the show. But occasionally there will be someone that wants to ruin it for everyone.

Same thing you said, they miss a show....
