answer: #Person1# thinks he lost his wallet at #Person2#'s restaurant. #Person2# helps #Person1# look for it but doesn't find it. #Person2# advises #Person1# to check if the wallet isn't at home.
documents: #Person1#: Hello. Excuse me.
  #Person2#: Yes. Can I help you?
  #Person1#: Do you remember me? I just had lunch here a half hour ago.
  #Person2#: Of course I remember you.
  #Person1#: I think I lost my wallet here.
  #Person2#: Oh, no. Really? I didn't see anything.
  #Person1#: Really? You didn't find a wallet?
  #Person2#: No, I didn't. Would you like to go look by the table with me?
  #Person1#: Yes, I would. It's not here. And it's not on the floor.Has anyone sat at this table since we left?
  #Person2#: No. It's been empty the whole time.
  #Person1#: Hmm. I don't know how it could have happened.
  #Person2#: I remember, sir, that your friend took the bill.You didn't pay for the lunch yourself, did you?
  #Person1#: No. My friend did.
  #Person2#: Then are you sure you took your wallet out of your pocket while you were here?
  #Person1#: No, I'm not sure. But I usually take out my wallet when I sit down.It ' s uncomfortable to sit on it. So I usually put it next to me on the table.
  #Person2#: Maybe you lost it before you came here. Or maybe you left it at home.
  #Person1#: I don't think it's at home. I think I had it when I left the house.But what should I do?
  #Person2#: Well, the first thing you should do is make sure it's not at home.Then, if it isn't, you need to call your credit card companies and cancel your cards. Next, you need to replace whatever you lost, your driver's license, things like that.
  #Person1#: Should I call the police?
  #Person2#: You can if you want. But the police usually don't do anything about lost wallets.
  #Person1#: Hmm. I'll go home and check. Maybe you're right. Maybe it's at home.
  #Person2#: I'm sorry we couldn't find it, sir.
  #Person1#: Thanks for your help.
