The only time I walk away, is when someone attempts to get considerably more work without additional cost or attempts to get a lower price than previously agreed'
This is common to a particular ethnic group and where I previously overquoted, slightly, to allow for the ' bargaining ' I got so fed up with it, I now quote the work at a rate which guarantees they will look elsewhere.
This is not bad business and I will not elaborate on a public forum, so you can draw your own conclusions.
