Hello. Is everything OK? Can I help you?
Oh, wonderful! You speak English! I need to exchange this foreign currency.
That's no problem. Is it cash?
It's Traveller's Cheques, is that possible?
Of course. If you could sign your name on the bottom line here, and write your address here. And please sign and date the back of every cheque and of course I'll need to see your passport.
Yes, right, certainly. Here you go.
