I've had this clown last year. He showed me £30 and I smiled and took it out of his hand and said where is the rest? He didn't have it obviously, I then said that's fine- I charge a 50% cancellation charge for time wasted in last minute cancellations and showed him the door. Oh he kicked up an awful fuss. The outrage! I probably shouldn't have done it but he was a chancer and about time someone took advantage back. Said he was going to the cash machine, could he have his money back?! Erm, no!
