answer: #Person2# asks #Person1# about a safety deposit box. #Person2# chooses the smallest safe box for the documents and feels comfortable giving the extra key to his wife.
documents: #Person1#: Good morning and welcome. How can I help you?
  #Person2#: Could you tell me something about safety deposit box rental, please? I need somewhere safe to keep some insurance documents ; I just simply don't feel comfortable keeping them at home or in the office.
  #Person1#: We have 3 different types of boxes. We usually rent for 1 year and the fee depends on the size and location of the box.
  #Person2#: I think I'll go for the smallest, as it's just for documents. Will I be the only key holder? I'd perhaps feel a little nervous if I knew someone else could have access to it at any time.
  #Person1#: You can have more than 1 key if you'd like, but we must have signature cards for each box.
  #Person2#: That's great ; I can give an extra key to my wife. I feel perfectly comfortable with her having a key. Thanks for your help.
  #Person1#: If you have your ID and are willing to pay a year in advance, we can do that for you today, there is no need to wait.
  #Person2#: OK, I'll take a small, for 1 year, in this branch, please.
