matt i think you just have a habit of winding some folk up maybe?
remember when you clipped that customers plant that was growing around a window?now if that was me id of left it and not cleaned that window.not you though!oh no!so what did you do?cut the thing down without the owners consent!
.i bet they were well happy!
yes some old folk are losing it a bit.i had one chap who slammed the door in my face accusing me of "ripping him off" saying i was "only here last week".he was losing it for sure.started getting angry every time i was round.he was suffering with dementia.i wouldnt dream of telling him to fock off though.the guy was ill.
ive also got a few customers that if anything happened to their wifes id drop them like a stone!(husbands miserable,moaning and clearly resent paying for window cleaning!).
if i were you id apologise next time your round.
there is a great youtube clip of an old geezer(retired boxer) getting hassled for money off a few young drunks.after a while he punches 1 of em and the other lad has a go and he floors him with one punch.he s out cold on the floor!
