Man: Exactly, but if the citizens are honest, they wouldn't mind, would they? So may I look in your bag, madam? We don't want to make a fuss, do we?
Woman: Fuss? Who's making a fuss? Stopping people in the street and demanding to see what they've got in their bags. Charming! That's what I call it, charming! Now go away; I've got a train to catch.
Man: I'm sorry. I'm trying to do my job as politely as possible but I'm afraid you're making it rather difficult. However, I must insist on seeing what you have in your bag.
