You'll always get the demanding type that want to see you work needlessly hard on a job, for the meagre rewards they think you are worth. It's usually the ladies of a certain age who haven't done much in the way of work themselves, and refer to us and gardiners etc as "I have a little man who...." Or those that think because a job has been done one way in the past it should always be done that way.
And they can keep their custom, thanks very much. Losing these types is a blessing, you can fill the gap with a better customer.
