About 15 years ago. An extremely toffy nosed rude customer owed me money. he had moved without telling me but still was going back and forth to the house to do maintenance and collect post.
I accepted I wasnt going to get paid, and whilst it was a tad annoying it wasnt a big deal.
however whilst I was cleaning the neighbours... they happen to mention that he had openly told them he had no intention of paying me ... his words were , " he is just a window cleaner"
I was really cross. my first job was working for a sign company where I learnt to do poster sign writing the old traditional way.
so I popped to the local art store , got some luminous paper about 3ft by 3ft. and did a proffesionaly written poster
it said
shame on you mr x
pay your bills
and I put it on his door
Later that afternoon my phone rang
DO YOU KNOW WHO I AM
I AM A PILOT AND A CAPTAIN
i AM WEALTHY AND LIVE IN A NICE HOUSE.
I just replied , I am a window cleaner and I need paying to feed my children , then I hung up.
A few days later a cheque arrived.....
I didnt pay it in , I put it in the bin.
I do chuckle to myself when I look back.
I certainly wouldnt react like that now.... however back then I had a young family and money was tighter.
