I had a guy warn me off his 'patch' a few months ago. He accused me of canvassing his customers, and told me he didn't want to see me working on the estate again.
I just told him that no one telIs me where I can or can't work, and also that if I were to be approached by any more of his customers, I would take them on. On the flip side I told him that if he picked up my customers, that's fair enough too!
Since then, I've picked up 7 of his in one terrace! He lost them because a) he's got a bully boy attitude towards his customers (he warned them not to go elsewhere), and b) he's unreliable.
