People watching is one of the most enjoyable aspects of being in England during the 2012 Summer Olympics.
Wherever you look, there are new faces and interesting places, and the volunteers and security guards are trying to have fun with all the crowds. They are using humor to cope with all the lines. Humor is helping the lines seem less intimidating, too.
Exhibit A: Just outside of Stratford Station, a main transporation hub, on a cloudy Tuesday afternoon, a tall volunteer with a megaphone cheerful said, "Welcome, Australians" and "Hello, Americans" in a pleasant voice. He asked dozens of individuals what countries they come from, and then said hello and repeated their nation's name.
