Just had someone in last minute who I've seen before. He paid, used my toilet and then said he changed his mind. Couldn't do it to his wife etc. He was nice enough and apologised, but I gave the money back and he left.
I'm aware that this happens and sometimes it's genuine. Maybe he didn't like me this time. But everyone else who has been genuine has left the fee or part of the fee and he looked like he was going to ask for it back anyway, so I offered and he took it. Said he wouldn't bother me again. I would have been more bothered if he'd disrupted my whole morning, but because it was last minute and 15 minutes, I wasn't too bothered.
Worth a report or not would you say? He hasn't got any reports so far.
