Chap next door to one of my regulars wanted an end of tenancy clean, said I would do it for double the price when I was next in the area.
He sent me ridiculous amount of texts insisting I had to clean it by a certain date and I informed him I wouldn't be there until past that date, Told him I wasn't going out of my way just for him and he got well annoyed. Told him to find some other window cleaner, don't mind end of tenancy clean if it's convenient for me but upsetting my routine just to please a 'one off', "on yer bike"!
