“I believe that any organization that sells goods or services should have an obligation at the first time they advertise or disclose prices to also advise what amounts of tips are expected.”
Restaurants are required to state that gratuity is included. This must be stated on the menus if not then you are not required to pay the gratuity. Basicly, it must be in print either on the menu or on a sign posted in the establishment.
