Black Friday 2007 at Best Buy at 5:30am. Despite the huge lines, employees kept things orderly and people got out quick. The banking queue model for checkout is old news at Best Buy, but it is pure process excellence to get people moving. I was also amazed how every time I had question about where an item was located, there was always a blue-shirt employee nearby to direct me. That's an awesome experience. Target or Walmart would have been pure pandemonium.
