I hope I'm not part of that subspecies. Liberty is reciprocal, and just because you hav ethe right to act a certain way, that doesn't mean it's right to do it. I have every right to flip off and curse out anyone I meet on the sidewalk, but that would make me quite the unwelcome individual. I have the right to never tip anyone. The tipping system in America is a weird tradition anyway. But it's also not cool to mistreat underpaid servers.
