Dear Janerowena, My window cleaner retired, so I hired one I'd spotted cleaning windows nearby. He did half a job, leaving one window worse than it was before he attempted to clean it: all cobwebby & streaky, which I only discovered after his departure. He overcharged me, and when I emailed to complain and suggested he discount the charge on his next visit, he declined. I don't suppose I'll ever see him again. Sorry to mention the 1950's, but they were a time when everybody, whatever their profession seemed to take a pride in their work. Tradesmen now seem to have got a bit uppity and patronising to oldies. That's been my experience, anyway.
