BEER MARKET

摘要

Usually, the only math required at a bar is tip calculation. But a new algorithm-based program from Miami company Drink Exchange makes ordering cocktails much like playing the stock market. If a particular concoction is popular, the software automatically raises its price. Conversely, the less popular a drink, the less it costs. Bar promotions (such as a sudden "market crash," when all prices fall) affect prices minute to minute. Television screens and LED tickers display the prices so patrons can follow along-and throw elbows to get their orders in.
