Years ago I was talking to a friend who was a TV repairman. He told me about a visit he had made to a very run down and nasty area, and when he went into the very dirty flat where the TV was he found the man and woman in a bed in the living room. The woman got up to let him in and then put the kettle on, made a pot of tea, emptied the cups and refilled them without washing them and gave one to my friend. She then made him a sandwich of some kind and gave him that. He didn't like to say no, as the man (still in bed) looked like a villain, and my friend was a bit frightened. He sat on the floor behind the TV, and after he had fixed it he put the back of the TV in place, with the sandwich inside, and then left as quickly as he could. For as long as he worked for the same firm he was terrified in case he ever had to go back there.
