I bet 99.9 percent of window cleaners have done daft stuff like the above at some time. I know I have and I've only been cleaning windows for a fraction of the time some of you guys have.
When I first started window cleaning; prior to this forum; I just assumed that doing stuff like this was part of the job description.
Also, you don't know the economic pressures those guys in the pictures are under.
I think forums, such as this, are great at educating us window cleaners in 'elf 'n' safety.
