Here's an unusual one.
Way back in November 2012, I did what was possibly a one off clean - though there was a chance of it being annual. As it was a large job by my standards (pretty much a full day), I was OK with this. It was sort of commercial - a very large house divided into flatlets - to be paid as one payment by the landlord. I issued an invoice as it was one of his businesses.
Anyway, it appeared that he bumped me for the money as my text reminders were ignored. Naturally, I was seriously p'd off about this but eventually started to move one. A year after, he emailed me to book in for the next clean. I told him no - unless it was paid up front and the previous clean was paid for too. I wasn't rude but my email was intentionally brief. I got no reply. It seemed odd. I figured that he just ripped off so many people that he forgot who he had done it to.
Today, one year and eight months later, he phoned me on my mobile to do another clean. He apologised profusely for messing me about, said it was overlooked, he had had some major life problems (won't put it on here as pretty personal) and some other stuff. So again I said I would clean but the two cleans had to be pre-paid. He offered to meet me with a cheque on the day but I wouldn't have that as cheques can be stopped. So, to the good old BACS transfer. Got in this evening and the two payment are in my account.
I may be wrong but I suspect that he may have had some sort of breakdown previously.
So, true to my word, I will carry out the clean in the next few days.
Just putting this on here as it's very unusual and thought it might interest someone.
