Markets can only be efficient if knowledge of prices for competing goods and substitutes can be known. Drip pricing makes efficiency really, really hard.

That said, this is less about efficiency in my view and more about getting rid of the dirty little FU on the bill and allowing customers to avoid a surprise.

Restaurants are substitutes in calories sure, but menus, locations, decor, service will differ. I’m not sure I need efficiency in this space in that regard.

However, once at a restaurant, I would like to have a rough idea when I order whether I’m in my personal budget for that meal. From that perspective, this feels great.

If one doesn’t have to think about budget given financial prowess, this law matters little. If one does need to consider their budget but doesn’t, this law also matters little.
