 Person1:      I see . Yes , the advertisement has proven very effective . Would you like to apply for a card with us ?  
 Person2:  Yes , please . But I suppose I'll have to open an account with you first , right ?  
 Person1:      That's right . But don't worry ; it's a very simple procedure .  
 Person2:  Could I open an account with you today ?  
 Person1:      Of course , it can be done right this minute . If you could just fill in this application form for me ? Do you have your ID card with you ? I'll need to see that .  
 Person2:  Yes , here you go . And sign here ?  
 Person1:      Yes , please . That's being processed now . As soon as the account is set up , we can issue you with a card .  
 Person2:  So quick and easy ! Thanks very much .
