Petrol on HP

After Church I drove straight down for petrol. I always take the right amount of cash plus coppers in case I go over.
Trying to hit the right amount is an art. Today In was in a dither and topped the gauge at an extra £2:95p Oops :( I always go there but they don't really know me but I assured them I lived up the road and would be straight back.That's what I did but parked in the supermarket and ran over with the money.
The reason for that is because when you leave the garage you exit left and have to drive up to the roundabout  and come back over.Loads sneak out to the right.
One time you were able to enter and exit the same but like everything they make things difficult ;)
