Richard Gray was a famous explorer. He was also a millionaire. He had visited every country in the world. He had crossed Antarctica, flown across the Atlantic by balloon, and climbed Mount Everest. Last year he decided to walk across Death Valley, the hottest place on Earth. He walked for days over the hot desert sand. One night he found the camp where he had been the night before. Gray had walked in a circle. He was lost.     Two days later he had drunk all his water. He couldn't walk. He crawled to the top of a sand dune , and there he saw a man.

A waiter in a shining white uniform came out of the door.     "Water...water...a bath! Food!" screamed Gray.     "I'm sorry, but you can't come into his hotel,"said the waiter.     "Why not?
