Ahh yes, the old wrong house trick.
I was once asked to do a TV aerial job for a guy who gave me some directions on how to get there and what the place looked like.
I get to what I thought was the place and the aerial there was in a VERY poor state of repair.
I found it strange that the key he gave me didn't fit the front or back door.
It didn't bother me that much as I had a field-strength meter with me at the time and could do the job pretty much up on the roof.
Anyhow, I'm up on the roof and the people that DID own the place came home, the guy didn't look the same as the guy I had been speaking to.
I really thought I was in trouble at this stage, having installed and aimed a brand new aerial and a mast-head amplifier.
Guy said to me "Crikey, that was a stroke of good luck, I've been trying to get someone out here for ages, everyone is just too busy, we've been putting up with terrible reception since the last big winds blew our old aerial to bits!"
"By the way, the place you're looking for is Dick's place just down the road, it was built by the same builder and it looks identical".
Guy paid the bill the next day, no worries.
