I look at everything that I pay for, that isn't a WG, in terms of a punt...
£120 fuel into the car? that's 2x 30 mins (or a cheap-ish 60mins)
£100 for a pair of shoes? that's an expensive 30mins or a reasonably priced 30mins and a flutter on the footy on the way home.
£1200 car insurance? that's the dom special when you get fucked hard and slowly all year - big fucking strapon. and just when you think you're done - the bitch tags in her mate who had lubed up her strapon in anticipation to pick up where her mate left off! fucking car insurance, con!
