On one job I was on with my mate there was a decorator who was constantly p1ssed and bad tempered for reasons known only to himself. He was also a nasty bully.
He was shouting at me one day about how I was holding him up,in his way, costing him money yadda yadda yadda.
A bit later that day I found some nice white gloss paint in my toolbox the problem being it wasn't in a tin. My mate helped me clean off my tools and went out for a smoke. Not long after the decorator came in shouting his mouth off threatening everyone. Somebody had poured 5ltres of undercoat all over the front seats of his van, the dashboard, steering wheel too and he wanted to know who'd done it. My mate was straight in and told him he'd done it as he'd parked it in our way and was holding us up costing us money, and punched the bloke off his feet.
Funny how quick a bully turns into a coward, he didn't want to fight but he wanted to know what my mate was going to do about the undercoat on the seats.
"F**k all" was the reply "You're the decorator, when its dry gloss it."
He was a changed man after that.
