be very carefull about falling out with him, I have a friend who fell out with his dog walker over exactly the same thing ie he wasn't walking the dog. He told the guy to get lost and didn't give him his last cheque a week later he was burgled suspicious I think so. Give him the 6 quid and tell him you've decided you can't afford it any more and leave it, it'll cost you more than that to fix a broken window if he pops back later and puts a couple through.
