One is an internationally renowned statesman; the other was a barman working at one of east London's hippest restaurants.
But it was the former Prime Minister, Tony Blair, who came out on top in an unusual clash on Friday. He managed to use his years of verbal dexterity - some would put it less politely - to talk himself out of what could have been a humiliating situation: a citizen's arrest.
Mr Blair is followed to almost every public engagement by protesters who blame him for the hundreds of thousands of deaths caused by the Iraq war and its aftermath.
The website arrestblair.org offers a bounty of about £8,500 to anyone who can "arrest" him for crimes against peace. So when Twiggy Garcia saw his chance on Friday night, he leapt into action.
The former Labour leader was enjoying an intimate meal with family and friends at the Tramshed restaurant in trendy Shoreditch, where Mr Garcia was working. The venue, owned by the chef and Independent columnist Mark Hix, serves only two main courses - chicken and steak - and has artworks by Damien Hirst on the wall.
