... and not to recommend you to anyone.
Four months ago I am cleaning the windows opposite this lady. She asks me if I would clean hers and said her last window cleaner stopped coming around. On questioning it emerges it's because she sent him away once saying she didn't want them done. I suggest to her that possibly that is why he didn't come back. Anyway, she says the last guy charged her £20 for every other month, so I say I will do them for that. It's a good price.
So today she comes out with my money and says her daughter has a bigger house and only pays £16. I say how often does she have them done... she says monthly. So I point out that I'm actually cheaper yet still keep her windows clean. Anyway, I get on and start thinking. So as I'm leaving I knock again and offer to clean her windows for £15. ..... Monthly. Oh no she says, we'll stick with the existing arrangement.
