I couldn’t reach the top of a boiler today. I was working on the fourth floor of some flats. Rather than go and get my steps. A customer gave me dining chair. Up I clambered. At which point it gave way. I fell sideways. Landed on the draining board full of stuff. Bounced off that and landed in a crumpled heap on the tiled kitchen floor. Luckily my head broke my fall. health and safety kids.
