This is nothing more than a cash grab. Few people will change their habits due to this pointless tax, and those imposing it are well aware of that fact.
They are after the revenue. Nothing more, nothing less, no matter what they claim.
This is going on across the country where, due to the policies of the Socialist Democrats which have resulted, in part, to the extraordinarily high level of unemployment (despite the lies of the obama synchophants), cities and counties which continue to pay high salaries and obscene pensions are desperate for money.
