Well gosh Dee Sa - this is an identical situation to mine!!! I too have had the winter vomiting bug, been left with a dreadful chesty cough like yours, and had a oily elderly salesman round who I could quite well do without, a nasty piece of work he was, who insisted he wasn't selling anything but "just listen madam I am working on behalf of the government doing a survey" It was obviously something to do with either solar panels, cavity wall or loft insulation but I never let him get that far ....... I was jolly annoyed as 5 minutes previously his wife (obviously she was as they introduced their "spiel" with their names) had also pestered us. I yelled at him and told him that I had a "No Sales calls" notice up, we were designated to be a "No Cold Calling" street therefore he was breaking the law and why did he not think to liaise with his wife on which houses they had called on. He was really rude and indicated that it was my fault that his wife had called previously "How am I expected to know that!" he said!!!!!! GRRRRR luckily my Hubby rescued poor coughing me, and told him to push off .......................!!!!!
