Some years ago when trad doing windows, I had this customer who was starting to anoy (?) me. I was just about to start cleaning windows and it started to light rain/drizzle, so I thought just carry on. Custy was in and could clearly see me. So I cleaned house and knocked for money. She started to moan about it raining, so told her shud have said something before I started not wait till end n moan about it. But she paid so kept her on. At another clean later in yr, went bk day after for money. Said she wasnt gonna pay cause frames were dirty, so I clearly havent done windows. Told her I clean windows not frames as I charge extra for doing them. She argued but paid. I decided she was now dumped but didnt tell her, just didnt bother doing them. About 4 mths later her fellow shouts across road, when my other customers were out in gardens, "Dont bother doing ours anymore!!" He thought he was a big man. So I shouts back, if you havent noticed ive left yours alone for last 4mnths for messing me around mate!!
I had a certain level of satisfaction that day, but regretted that I didnt man up and just told them at the time of deciding. Im sure I wohld have still been satisfied. Infact, that point onwards I let them kno to find somebody else who will dance to their tunes, when Ive decided to drop them.
