i have the occasional one where the gates are locked with no back access and get sick of knocking so stopped in the end,
had one guy who expected me to go through his neighbours garden and over a 7 foot fence to get round the back!!!
when i said i wasnt prepared to clamber over this fence he started ranting about how if i didnt want the work this was fine,would be after id done the front wouldnt it,never got paid and he started banging on about he used to be a window cleaner and he use to have to do it to earn a crust,
more fool him turned him into a misserable tw*t dint it
