Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. If the conversation begins with a question, label it '1' otherwise '0'.
Input:  Person1:     Have you got any specific proposal about the terms of payment ?  
 Person2:  I wonder if we can make payment for this order by documentary collection .  
 Person1:      I'm sorry to say the only term of payment we can accept is 100 % irrevocable letter of credit payable against shipping documents .  
 Person2:  But our order this time is very large . To open an L / C for such a large amount at a bank is costly . Can you be a bit more flexible and bend the rule a little ?  
 Person1:      I'm afraid not . We insist on a letter of credit , because as seller , we also have the problem of funds being tied up .  
 Person2:  To be frank , a letter of credit would increase the cost of my import . When I open a letter of credit with a bank , I have to pay a deposit . That will tie up my money and add to my cost .  
 Person1:      Consult your bank and see if they will reduce the required deposit to a minimum .
