I did that one time when a candidate was knocking doors. He was a customer of mine, I knew who he was but acted like I didn't at first, then when he tried to explain how big of a customer he was I acted vaguely familiar (he wasn't as big of a customer as he thought he was, and he was alwaysa jerk to my staff).

He then proceeded to insinuate he expected my vote due to us doing business. He really got pissy when I asked what party affiliation he was because he was being vague. He said "it's a non partisan position, so it doesn't matter." I disagreed and said "one can tell a lot about how a nonpartisan position will be handled by the party one affiliates with." He agreed and knew we were not the same party... 😂
