OK, I have never run a business.
What I loathe are the emails businesses send you after they have completed a service. For example, I used a Locksmith Company (recently) and a Roofing Company (perhaps a year or more ago) and they now want my input as to how they did (even the roofing company).
I have done one or two reviews, but lately I have thought. Where is this going to end up? How long will it take me?
So don't bother.
