I am always surprised that in the US, with all its consumer protection laws, businesses get to advertise prices that are misleading. You have to pay the minimum service fee, or you'll get into a loud argument. You have to pay tax too of course, but it's added to the bill separately, which makes it inpractical too: buy a coffee for USD4, and you have to pay an impractical amount like 4.36. I always suspect this is a ploy by businesses to protest these taxes.
