I like the confidence that the employees had to get the stopwatches out for the 8 second test.
The difference between US and UK culture is jarring. In the U.S. if we don't like something we just shrug our shoulders and walk away. In the UK they openly decry the product's existence. And their politicians love to verbally spar. Here politicians passive-aggressively don't clap during state of the union speeches. I love it.
From what I've seen people in the UK try to be very 'proper' about everything - often when they don't even mean it. That's what causes all the differences in culture between the UK and other European countries like Germany.
Although, this is the Government that promoted the slogan 'Keep calm and carry on'[1] many many years ago.
