A Canadian who demanded courtesy from a U.S. border security guard says he was pepper sprayed and held in custody for three hours for asking the disrespectful officer to "say please" when ordering him to turn his car off during a search.
"I refused to turn off the car until he said please. He didn't. And he has the gun, I guess, so he sprayed me," said Desiderio Fortunato, a Coquitlam, B.C., resident who frequently crosses the border to visit his second home in the state of Washington. "Is that illegal in the United States, asking an officer to be polite?"

I've seen such agents who were downright surly, but that just takes the cake!
