In no particular order:
Fly poo on the glass
"Can you leave it this time"
Hydrophobic glass
Spider's webs that just won't shift despite aiming the jet at them. Scrub, flick, scrub, flick...
"It's never 4 (6/8/12) weeks is it!?"
Dripping vents
That stiff, inflexible Gardiners yellow pole hose
Water freezing on the glass when it's frosty
"You've missed a bit ha, ha"
"Excuse me, are you a window cleaner?"
Did I mention fly poo?
Leaving my hot mug of coffee in the kitchen when it should be in the van
Late payers
PayPal's charges
Putting the reel on a high-spot that means you can't wind it in 'cos it catches on the ground
Adverse weather of any kind whatsoever
"Can you do me a favour whilst you've got your brush out"
Inaccurate weather forecasts
The hose getting caught on car tyres/ the corner of a building/flower pots etc.
People who go out without paying you as they go.
Fly poo
Mind you still the best job i've ever had
