Hi , my oddest job was a rewire in a house the customer was going to vacate for a week in return for a 500 quid price reduction. On the second day a builder turned up, saying he was to knock through from through lounge to dinning room and into the garage from the hall to allow a downstairs toilet. At this time all the old had been chopped and a nee board fitted with a couple of surface sockets for us. Was a bit peeved but thought just get on with it.Next day returned to find old lounge door now bricked up, New door cut but brick not knocked out.
I probably should have guessed as a few years earlier when rewiring the customers mates house, same empty house deal. Got there on day one, concrete floor clear , no furniture, excellent. Not quite it was all upstairs filling and covering every board.
Neither offered the discount back.
