Wholefood's Waiting Line

(1/22/2013) People don't like to wait, however, we wait quite a lot in our whole lifetime. Coffee shop, highway, bus, cross the traffic line, surfing internet.... Supermarket's checkout is often configured as a multi-waiting-line system. Customers often find a line with a shortest queue to load their grocery on the belt; however, it does not guarantee you will be served earlier than other customers who come later than you. Do you see the lady in front of you just takes out her check book? Gee....

Wholefood's shop in New York City changed its multi-queue system into a single-queue system in 2007. Read this article to see how their customers react. Very interesting.
