Quite honestly, I think it would be beneficial in the long run if restaurants and other businesses were to add line-item details reflecting each customer's share of the various taxes and fees the government imposes on them, directly or indirectly. Particularly in liberal areas, the average person seems to think that all of these government mandates are costless - that businesses are some sort of magical bottomless money pit, with greedy owners hoarding all the lucre for themselves until the paladins of government ride in to free it for the workers - and putting line items like these on their bills is simply a way of demonstrating, in a very personal way, that all of these mandates have a cost, and that the cost ultimately comes out of their pockets.
