A lady customer some years ago claimed I had scratched her window. So I asked if I could take a look from the inside, and sure enugh the scratch was on the inside, her face wa a picture as was her husband's.
Another lady rang up and complained that I had left her windows dirty and she was not paying, so I went to check and the back patio window was a right mess, dirty water had run all over the door and thee was no way I had left it like that, I looked around and saw an old bucket ith the remnants of this dirty water still in it. I told her someone must have thrown dirty water over the door, but she laimed noone had been in.
I had seen some young lad in the house on the day, bu she swore blind noone was in.
I re-cleaned this door for her and she paid me, but tried it on again some months later, claiming I hadn't done them at all, I told her that her sons wer in on the day and they would confirm I had done them, and she insisted there was no way that her sons were in, and that I had not done them. I said that's funny 'cs not only were they in, but they paid e as well.
I decided to drop her, but left it for a few month's before I informed her.
I pu up with quite a lot but this lady was basically calling me a liar
