Every day in summer 75,000 people sail away from Dover across the Channel. Each ferry goes backwards and forwards three times. It can get very confusing to the crew - sometimes they have to ask passengers which way the boat is going. The passengers have their own problems. The Wallys, for instance, are trying to get to France. Trouble is, their car has broken down three times so far. When the ferry docks at Calais, Pru Lobbard isn't queueing to get off. She's only here for the duty free. "Well, they rip you off in France," she says, "and then there's all those dogs with muzzles..." Day trippers sing on in the bar, a nun buys her spirits allowance, and the chef fries the Dover sole that comes from Calais.
