weve recently had a client swear at our staff, told them it wasnt satisfactory to swear at staff and cancelled cherry picker on site and refused to continue to work on site until it was all cleared up and a written apology was sent, this wasnt a bit of banter it crossed a line, apology recieved and working back on site, dont let people be abusive to you or your staff, no where else accepts it, neither should we,

jack , dont have none of it .

block his drive off with one or two of your vehicles

and dont back down when he says he is going to call the police, let him 

he will soon back down.

then move on 

some will disagree with me on this 

but a bit of intimidation works wonders

I'd smash their face up with a cricket bat...

That'd be if they didn't stump up for six cleans, not four. You've got to have boundaries.

That might sound good but I think you'd be on a sticky wicket letting it go more than one or two cleans. Any more than that and they might bail out. You don't want to make your window cleaning run a hard slog do you?

You need to block your customers from treating you badly so keep a straight bat and don't be tempted to let down your guard especially if a couple of bouncers come your way.
