I  travel an awful lot, and I can honestly say I’ve experienced most of the world’s travel systems, so I like to think I’m a bit of an expert. I’ve taken taxis in New York, where it’s practically an Olympic event, and flown on most major airlines, and I also have to drive a lot when we’re filming ‘At Your Service’, so transport is my speciality! I think that transport is the thing that’s changed most since the early days. Certainly air travel used to be a high-class affair, full of glamour and expense, and now it could hardly be more different. With everyone squashed into tiny spaces nowadays, behaving well has become more.
