I have a guy coming to do work for me today. This was booked 5 months ago as this was his first available date. I will be there this morning to see him and discuss the job but I'm after been given an appointment in the hospital this afternoon which I cannot miss. The job should be finished before I get home but I'm worried about paying him in full until I see the completed work. AIBU to withhold some of the money say half until I get back and ensure the job is done or should I pay in full and take the chance? There is no one around that can pop in and check and he is not local to the area.
