Df is a builder, and has been for 42 years. Couple in question are having their garage converted. Df has spent a fortnight on the job, it has passed building regs, but customers are now saying a window is wonky so they won't pay him. In actual fact the existing brickwork is pissed, window is straight.
Df is mortified, in 42 years he's never had a complaint or been knocked. Do you think shame would make them cough up or should he just accept that he's worked for 2 weeks for feck all? ( and paid for the materials) grrrrr
