Yeah ive got a few like this but I give them back exactly what I get.
One tells me not to bother no more as he will do em, so next month I go back I knock on door and missus comes out and I ask if she wants em done as hubby said leave it, and she says yeah he told me what he had said, but he wont do em , so carry on doing them,. She then said she was going out so when finished knock and he'l pay you.
He comes out all sheepish, pays me, I just smile at him take me money and walk off.
Love it!!
