Staring at the rude boys
This i think is your strongest point. With the different tarrifs, what reasonable person would pay over twice the amount. Is it worth noting that £3 for 5 hours is still more than the price for 2 x 3 hours which would only come to £2.40.
Well spotted. The OP could make the argument that the Landowner has suffered no loss and the action is vexatious opportunism.
