After a long day on the trading floor, this bar will make them feel ... back at work! Behold, economics at work with The Drink Exchange, a bar pricing system where the prices change in real time based on supply and demand (if no one buys a particular drink after a while, the price for that drink goes down)
At programmable times, the system can simulate a "market crash" to drive sales. Link
Apart from the novelty value, it mostly meant that drinks were usually pricier there than anywhere else.
The waiters never pay attention and by the time they enter your order the prices have gone up.
When there´s a crash, there´s not enough waiters to take orders.
And then. Price on Fosters may drop to below zero, there´s no way I´m buying that stuff.
