Have you anything to declare ?   One bottle of perfume and a watch .   Where did you buy it ?   In Boston .   Do you travel a lot ?   Oh ... I go to see my sister twice a year or so .   Twice a year ? How long has your sister lived in Boston ?   Nearly ten years .   I see , that's a long time . How much was the watch ?   I can't remember , but I've got the receipt somewhere . Would you like to see it ?   Yes , I'd like to see the receipt . Oh ! I see you bough the watch last week .   Yes . Does that mean I'll have to pay duty on it ?   Yes , I'm afraid you will . Altogether on the watch and the perfume you owe me seven pounds .   Ok . Here you are . Is that all right now ?   Yes , that's fine . I hope you enjoyed your stay in Boston ?
