Has Britain become a rude nation?

Julia Hartley-Brewer, who's no stranger to controversy, has found herself in hot water again after tweeting this conversation she had with a cab driver: "My Uber driver just proudly told me that his car has "zero emissions". I replied "I couldn't care less." Now he's looking sad".

Many on the social media site were quick to criticise both her apparent rudeness and the way she tweeted about the incident, but she claims she shouldn't have had to listen to the driver's "eco politics".

A predictable Twitter storm followed which included this comment from Jack Monroe: "The Waiter Rule: If you want to know someone's true character, look carefully at how they treat service staff."

They both joined us this morning to debate the issue.
