Thus governments can step in an enact truth in advertising laws, anti-fraud laws, etc. In my current example, most customers do not know they they are being served considerably less than a pint and when informed of this, often react in outrage.In a second post, he offers an obvious solution:
The British have been requiring a government stamp on pint glasses used in pubs since 1699 to assure the 'punters' that they are getting a right measure of the best bitter.
