Excuse me , sir . Is there anything I can do for you ?   Yes . I'd like to change some money , please .   All right . How much would you like to change ?   Let me see . I think maybe 600 USD at least .   Pardon ?   Six hundred US dollars .   I'm sorry , sir , after 7   But I am badly in need of the amount . Might I ask you to make an exception for me ?   I'm afraid we cannot help you , sir , because that would be violating the regulations . I owe an apology for doing nothing about it .   It's just too bad . I have to leave it as it is , and thank you just the same .
