I have one which was every month between April and end of Oct, beginning of Nov. Normally I don't entertain these types, just dump them, but I have known the family for many years, so just kept it on. This year I'm a bit late ,as weather in April was crap, so I went a couple of weeks back, and he says, we haven't negotiated the price yet. I said the price doesn't need negotiating, it hasn't gone up since last time. Cutting it short, he had been talking to others in the village and discovered they were only paying a fiver for a flat, his is a farmhouse.and £15.
So because I wouldn't reduce the price, he only wants them done every other month, to make it "balance out". So come October, I will make it the last time, 3/4 times a year? Not worth me bothering.
