Nah, the particular subspecies I am referring to are the ones who are almost violently possessive of their freedom, while lacking the intelligence/insight to understand the concept of reciprocity. Somehow, they believe that their "right" to freedom includes the "right" to not have anyone disagree with them.
The tipping system is weird, and I say that as someone who grew up without it. Frankly, I prefer the price on the tag being what I have to hand over... be that sales tax, my cable bill or the bill at a restaurant. But that's not how it works, so I deal with it!
