I had to buy my first new tv in 10 years after my current one went all weird. Everyone went all blue, it was like watching "NCIS: Pandora".
I stopped off at a nearby store and found a tv I wanted. While I was buying it I decided to take the 5 year warranty as well. While I was filling out the paperwork, a different sales assistant (not the one I was working with) sidled up to me and said "Don't put your physical address on the paperwork. Else two days later you'll get broken into and your tv stolen" and then slid away again before the sales consultant I was working with came back with the paperwork.
When I filled in the warranty paperwork I put in my postal address. He several times insisted that he needed my physical address. I pointed out that the form clearly asked for the address on my tv licence, which was my postal address. He insisted it meant my physical address instead. I refused, he looked pissed, but I got my tv without giving up my address. Too bad, so sad Mr Slimey.
