The Trader Bar in Melbourne, Australia is a bit different from your normal drinking establishment. Above the bar is a row of TV screens which show the price of drinks, which fluctuate as shares would in a stock exchange. Each drink is listed next to a neat little graph illustrating if your drink price is on the rise or fall.
Should your drink drop, it's time to get to the bar asap, as it's not going to stay too low too long. That is unless the staff purposely 'crash' the 'bar market', the background music being replaced with an enormous crashing sound and all drink prices plummet to their lowest.
