Passage Four As he closed his service station at 1:20 one Sunday morning, Tony Payseur set on the ground a metal cash box containing $7000. At home a short while later, he reached in the back of his car for the box. It was missing. Realizing that he must have left it outside the station, Payseur speeded back. The box was gone. Sunday morning; although he felt iii, Payseur went to work with his two sons. Then, in the middle of the afternoon, a man named Wayne came and told his story. Passing the station minutes after Payseur left the previous night, Brazzell had spotted the metal box. Thinking it was a tool-box someone had left accidentally, he stopped and picked it up. About 3 p. m. Sunday, Brazzell opened the box. Finding it filled with cash, he rushed to the station. "I couldn’ t believe someone would be so honest," Payseur said it when he got back his box.
