Some who haven't paid me for whatever reason are still good custy's
Sorry, thats a bad customer isn't it?
No
Some I have cleaned for years and for example they feel the back didn't get cleaned
because of no footprints in snow

[this was two days later]
Gate latch broken because of careless window cleaner [or the wind]
They definitely paid [ no they didn't ]
Gate not shut properly dog escaped not paying [no latch kept shut by plant pot]

These are just some examples of custy's who didn't pay and I still clean
and to be fair are good custy's.
Sometimes they have bad days then along comes the windy man

and I'm pretty sure with time to think most know they were wrong so
try to make up with a tip or fascia clean, gutter clean ect
Don't get me wrong if they tried it on again they would be dropped.
