Take some good solid advice from STEED, tell them to...............
"Go to bloody Hell you interfering Bastards."
Yes I had a run in with one of these swine in a Museum who accused me of being a pervert taking pictures of kids, I told him to go to bloody hell and if he did not retract that sick remark I would have him for slander.
I followed it by saying, lets both of us go to a one hour photo service where he will see my photos are of the museum exhibits and not kids. He soon backed down and said sorry, I am fed up with this rubbish that we have to put up with in this country.
