Cashier:                Good morning, madam. Woman:  Good morning. I
have a little problem. I'd like to buy some books from America but I
don't know the best way to pay for them. What do you recommend?
Cashier:        Well, you can give them your credit card number, or
you can make a transfer. It's probably better to make a transfer.
Woman:  Is a transfer very expensive? Cashier:        No, but there is
a small commission.
