How much do you put in your car at any one time?
My Mrs seems to put £10 - £15 in the tank 3 or 4 times a week and makes no sense to me what so ever...... While your there, and if it's a good price, brim it to the top and refill when it's empty, I cant think of nothing worse than filling up all the time, I would have to do this around 8 times a week!
Also while I'm having a rant, why the hell do people not pay at pump when at a pay at pump, they walk in with the card and pay in there! DUMB ass people, this really annoys me...
Had a guy put £20 in his car this morning in front of me, walked in to pay, by which time I put £69 odd in, got back in the car, started the engine and just banged my head on the steering wheel.
