I think my purse was stolen sir.
Do you have any reason to believe that your purse was stolen?
Oh yes, I left it on the table 20 minutes ago and then I went to the restroom. But when I came back 15 minutes ago it was gone.
Are you sure you left your purse on the table?
Of course sir, I plan to pay the bill before I went to the restroom.
Is this your purse? We found it in the restroom.
