Rory Sutherland had a good description of this:

"If you’re a top executive, turning up to work on a bicycle is a high-status activity because it was a choice and not a necessity. But if you work at Pizza Hut, turning up on a bike means you can’t afford a car."

Other examples include the clothes that Rory Sutherland wears during interviews, the ways that Rory Sutherland sits on chairs during interviews, and the ways that Rory Sutherland rambles over others during interviews.
