Surely noone in their right mind would buy fuel at White Post

Robbing bastards that's for sure. Back in the first fuel protests (2008?) they put their prices up to £2 a litre when it was nearer £1 a litre normally.

I might buy a bottle of milk there once in a while, and my friends sometimes take their mud caked off roaders there to block White Post's drains with the pressure washer rathern than their own , but not one of us give em a penny for fuel the cnuts

Shoulda popped round here, I've got a few jerry cans of Momentum for occasions just like you mentioned - quicker than popping to Tesco / Shell when you're just after a top up!
