Really, it's just an asshole tax. Most restaurants these days have extra fees that exceed 2% just because. Hell, once upon a time, a 15% tip was given for great service. Now it seems like 20-22% is often the lowest in the recommended tip section. 2% of extra money is nothing, especially when the fine is less than what was earned from the infraction. It's a lot easier to stomach a 2 billion dollar fine, when you earned 4 billion because of it.
