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.
