One day a man stopped at a Detroit hotel. He... (just to cash) a check, but he didn't want to carry too much money with him. So he asked the desk clerk to put a hundred-dollar bill in the safe for him. The next morning the clerk said that he... (not to take) any money from the man. The man had nothing to do but to go to the nearest lawyer. The lawyer advised the man to return to the hotel with him and to give another hundred-dollar bill to the clerk. That was what they did. An hour later the man went back and claimed his money. As the man had a lawyer as an eyewitness to the second hundred-dollar bill, the clerk couldn't say he... (not to take) it. Another hour later the man and the lawyer came up to the clerk and asked for a hundred-dollar bill. This time the clerk said he ... (already to give) the bill to the man. But the lawyer insisted that he (to see) the man giving the money to the clerk, but he ... (not to see) the clerk returning the money. The lawyer promised to call the police if the clerk ...(to forget) about the bill. The clerk realized that he could do that he co nothing but return the money.
I don't know how to thank you for getting my money back, said the man happily. Oh, don't thank me», answered the lawyer. My help will cost you one hundred dollars.
