Fargo,

No place can legally charge you a 20% tax, 16.5% is as high as it goes. If you are adding the tax and service charge (if there is one), then that is not 20% tax. A 20% tax is illegal and the business will be shutdown extremely fast.

As with stores, restaurants and bars can include the GCT tax in the price, but then they have to backout the appropriate GCT amount.

Firefly is one of the oldest establishments on the beach, they probably have the lowest GCT rate anywhere. But they have to backout the tax they owe. Trust me on that one, I spent the major part of today with the tax office. Just another crummy Tuesday.... (sorry Bangles).
