In California, restaurants were sneaking in 3% upcharges. They started out as "we're adding 3% to pay the state-mandated health care costs for our employees." It quickly progressed to "we're add 5% to your total bill because fuck you."

California recently mandated that practice illegal and requires all "extra fees" to be reflected in the prices instead.

Multiple restaurants stated (in public... recorded on TV, no less) that they "would lose business if they stopped this practice because then customers would know how much they're paying up front."

I was amazed at their candor. These "entrepreneurs" don't even know how to be embarrassed by their greed anymore.
