Bell : No, I won't. It's half past five. All the wardens have gone home. Ann : Ben! Ben : Yes? Warden : Is this your car, sir? Ben : Oil, My! Well, I'm sorry, sir. I'm just looking for a ear pork around. Ann : Yes, he is. And he doesn't know the way well. But can you tell us where we can find a parking space near here, sir? Warden : There's one an the comer of the second block. But don't park your car by the roadside next time, sir. Ann : No, no, we won't. Thank you very much, sir. Ben : You're really good, Ann! But we have to hurry, I'm afraid. We must get back before 6. Ann : But you mustn't drive too fast. Ben : Take it easy, Ann. Don't be anxious. Ann : Look, Bea! A police car is following... Policeman: Excuse me, sir. May I see your licence? Ben : Of course, sir, Well, I'm sorry I've left it at home. Policeman: In that case, you'll have to take it to the police station within five days. Ben : But... but why? Policeman: You were speeding, sir. Ben : But I was only doing 35 ! Policeman: There's a 30 miles an hour speed limit on tiffs road, sir. Ben : Is there? I didn't see the sign... Policeman: Well, sir. We've been following you. Ben : So you were doing 35, too. Policeman: No, sir. We were doing 60 miles an hour. Otherwise we couldn't catch you. (23)
