How to handle picky customers:
- do as you are told
- fire your customer
Seriously there isn’t many choices to choose. This is because most “picky customers” love to edit your work and present to you as a “sample” although it is not a sample.
It is what they expect you to do, which they have done it for you so that you can follow exactly what they have done (and they pay you to do this).
Why hire you in the first place, if they can do everything?
p/s: I am thinking about picky freelancers. Might write something about this soon.
