Previously, I'd only ever heard any mention of contracts on this forum untill last September.
A lady saw me window cleaning and asked me to give her and her neighbour a quote which I did. They were happy with the price etc etc for a 4 weekly clean and I was more than happy because they were right near where I have other jobs.
These ladies told me about a window cleaner who'd given them a quote a few weeks before. After agreeing the price, he produced a 'contract' that he expected them to sign which included a charge if either cancel one month for any reason and a charge of 3 months money if they cancel the 'contract' with him any time in the first year plus other bits that I can't remember.
One of these ladies told him to stick it where the sun don't shine and they both said that by the time he left with his 'tail between his legs', he looked like he was about to cry.
The reason he'd called round was one of these ladies had replied to a very shiney proffessional looking leaflet that had been put through her door. She said that when the window cleaner called round, at first she thought a BT van was pulling up onto her drive but then realised it was in fact a window cleaners van. After a bit of discussion, to me it sounded like a brand new 'reach and wash' van.
Anyway, I told these ladies that I also have a contract and failure to follow the said terms and conditions has dire consequences. The terms of my contract with them is that it is compulsory to provide me with a cup of tea.

Since then I've cleaned thier windows 7 or 8 times with no problems at £20 a bash each. What an idiot that other window cleaner was.
