Are you fed up with the customer service at a local retail store? A New York group demonstrated how to hit them where it really hurts: launch a real world denial of service attack by invading the store with people dressed like sales clerks

New York prankster group Improv Everywhere recently targeted  Best Buy, a US chain of electronics stores, by doing just that. They dress up in the firm's token khakis and blue shirts, and confused the hell out of both customers and employees.

Fact is that quite some people dislike Best Buy, so the prank got quite some support.
