Late one Sunday a customer walked into the store and asked for a pack of cigarettes. Mr. Bush reached into the display and handed the man a pack, which happened to cost twenty five cents. The guy opened it, took a cigarette out, and lit it; again, it was no faux pas to smoke in a store back then. Next he drew his wallet out of his pocket and offered Mr. Bush a twenty. A Canadian twenty. "It's all I've got," he explained smugly. What he was trying to do was get American money in place of the Canadian without the trouble of going to a bank or currency exchange.
Mr. Bush didn't say anything. He merely reached under the counter, took out an old cigar box, and gave the man $19.75.
It seemed Mr. Bush had accumulated a bit of Canadian cash over the years and had kept it for no particular reason.
But things happen for a reason. In this case, to teach a smart aleck a lesson.
