ive only ever had one customer try not to pay me for a patio I laid 15 years ago....I gave him 3 days to pay or his patio would be crazy paving..he paid....don't do courts..I do it my way...I learnt a lot from my first ever job fitting double glazing..bloke i worked for was a nutter..he took a whole house of windows out once..from the outside ..coz he never got paid :yikes:in them days stupidly the glazing beads where on the outside.
