Does anybody ever think to pull forward when they have filled up and there is a queue behind them at the pumps?
Or do you (like the driver in front of me) collect your handbag, carefully lock the car, head off to pay, come back to check the number of the pump, queue at the counter (possibly) buy a snack or bar of choccy, use the “facilities” all before paying and then not even notice the head of steam coming out of the car waiting to take your place at the pump?
No? So it wasn’t you who kept me waiting and made me 15 minutes late this morning then?
Seriously, how hard would it be?
