If 3 people have verbalised the complaint then 30 will have thought it but not wanted to say.
I get through jobs quicker with my son working now , and charge a lot more because he said I was too cheap.
I do the walk through at the start of the job , a have standard patter ,,,,, Have you got any spots , stains , marks or problems you want particular attention paid to? As there are 2 of us this job will take 2 hours , I have no sugar , jared has 2 .
At the end of the job I always stress that I am more than happy to return to any problems or issues they may have . I have been back once to a job this year , which means 10 people were not happy.
