I went to one today, set my gear up, started wfp and the owner comes out and says could he leave it as he cleaned the windows 2 days ago knowing full well I was due yesterday but I was behind by one day. I said he could but I would charge him a cancellation fee as stated in my T&C. He didn't like it, tough.... he paid, Time wasters do my head in. No doubt he'll find that trad cleaner who keeps dropping leaflets in his door. The trad guy is welcome to him as I don't need time wasting custies. Works both ways with wfp.
