I once ended up selling an old lawn mower
to some bloke who cold called me flogging double glazing.

Nicely done!
I once had a cold call to sell PVC double glazing. We already have double glazing throughout, he would have seen it as he walked up to the house. He knocked on a PVC double glazed door. I took the piss out of him, slightly.

But, that's commitment.
