About a year ago, I went to stay at a Detroit hotel. I didn’t want to  31  too much money with me, so I asked the desk clerk to put a hundred-dollar bill in the safe for me.
The next morning,  32 , the clerk said that he knew nothing about my money. I didn’t have any proof  33  I had given the man the money. There was clearly nothing left to do but go to the  34  lawyer.
The lawyer  35  me to return to the hotel with him and give another hundred dollar bill to the desk. So we did. An hour later, I went  36  to the desk and asked for my money.  37  I had the lawyer as an eyewitness to the  38  hundred dollar bill, the clerk could not say he  39  nothing about it.
Another hour later, I put the second part of the lawyer’s  40  into action. This time both the lawyer and I went to the hotel to  41  for the hundred-dollar bill once again, and  42  the clerk insisted that he had given  43  to me, I said it was not true. The lawyer said to him, “ I  44  this gentleman give you a hundred-dollar bill. If you don’t hand it  45  immediately, I will be forced to call the  46 ”. The clerk realized he had been  47 , so he gave me back the first hundred-dollar bill.
“ I don’t know  48  to thank you enough for  49  my money back.” I said to the lawyer. And what do you suppose he answered? He said, “ Oh, don’t  50  me. That will be one hundred dollars, please.”
