As a gas engineer I hope that this will happen, the nearest I have for to it is spending a night with a new customer last year - a week after I serviced her boiler
Ive been trying to get Bev do this but she is reluctant in our own home although she was tempted a couple of weeks ago when a fit plumber was working at our house. But she didnt give in to temptation and common sense prevailed..... Bloody common sense lol
