On the way back from the TOR 4x4 show I stopped for diesel at a Tesco's garage in Stafford and tried to stop the pump at £63 but it went over by 1p, I thought bugger. It was definitely on £63.01 when I left the pump, but when I went to pay the total was £63.02, they must make a lot of profit with these extra pennies, this seems to be a fairly common occurrence. I know it's only a penny but it annoys me, I complained but the cashier wasn't having any of it.
