Have a wank, smoke a cigarette then just go to bed.
Take you clothes off, get in your car and drive to a petrol station (try not to crash and kill somebody or get caught by the rozzers). Get out of the car, all casual as fuck despite your nudity, get some petrol and go into the shop. Pick up a Mars bar for yourself and a couple of cans of coke too. Better get some fresh bread for tomorrow morning. Proceed to till.
