Just walked home up our road and there's a guy loading some Prochem chemical, a bucket and a single jet, non-swan-neck wand into his boot and some small tub-like machine on the back seat of his saloon.
Said to the lady, "Hope he's done a good job?"
She said,"Nothing but the best, he's my brother. Why do you ask?"
"I'm Dr Carpet."
"O, yes" she says, "You live somewhere around here, I think."
"Yes. You can see where my (sign-written) van is parked; thirty yards up the road"
(And where it has been parked for the last 10 years.)
