I must have explained it wrong. He was the one who brought up politics, and also asked for my opinion about it during that interaction. He was clearly not in a rush, having come over to my table to ask the favor, and lingered here while mainly sustaining the conversation by himself, while I merely gave short answers to everything he said, partly to let him exit at any time to use the restroom, and partly because I neither expected or particularly desired a conversation, though I was okay with it as long as he wanted to have it.
