I didn't remember my first paying customer when I started reading this thread but reading your post Slacky has brought it back because I started with a friend. He still is a friend but I don't see him often. However, I remember thinking on the very first house we did, a three bed council house, "this isn't going to work." We were using leathers and scrims back then and he was so slow. I wasn't quick, but by the time I'd finished the downstairs of the house he was still doing the first pane of glass he'd started on. So after a very short period of time we split the work we had 50/50 and went our separate ways. He didn't stick it though and I'm still at it 41 years on. There's been a few changes since those early days of bicycling, wooden ladders, leather, scrim and 45 pence a house.
