I have invented a street based vending machine that dispenses alcohol in one pound shots. So, say you're walking along, you're on your way to a job interview and feeling a little nervous, you just pop in your pound coin and are delivered a small but potent shot of booze to settle your nerves. If you do well in the interview you can treat yourself to a couple more on the way out, or if you really muck up you can drown your sorrows.
