I'm more ok with "hidden" taxes, because the business is supposed to just hand that over. If they're putting something on the receipt that says "tax" and its not associated with an actual government-applied tax, that's just fraud., we don't need special rules to address that (yet). Its not hidden in an attempt to trick you into buying something at a higher cost. Its hidden because calculating the taxes requires additional information from the user.
