Chris Evans - monumental douche, may have been the drink though.
Gary Lineker - surprisingly tall! Didn't really speak, seemed ok though.
Top Gear presenters at various times, Clarkson is a bit up himself, Hammond is a genuinely nice bloke and James May is very abrupt when he wants something..
Most of the McLaren technical staff and drivers - Hamilton and Button - both of them very nice guys.
Also Jake Humphries, Martin Brundle, Eddie Jordan, David Coulthard.
Can tell I used to work in a pub owned by an ex-racing driver..
