So I'm going to chop it off!
Had these custies for three years now when one decides to try the 'not today' trick.
I let it go the once then next door did it then one up the road. Pulled up today, hitched my hose and had the brush on the glass, one of the windows was open so I tapped the door to ask them to close it. 'Not today thank you' argggh! Spot the neighbour over the road and asked him if he wanted his done 'yes please'. Started to reverse my van to the drive when he taps the window 'mrs says not today'. Stuff the lot of them, that's five more going in the bin unless I cool off in the next few days.
Had another one - 'not this time - you're stressing my cat!'
