If you read the whole section it specifies more than just "sold and consumed". In NC, ABC stores are run by the state, so only state employees work there. So sections 1 (state property), and 4 (state offices) may apply.
1. any area prohibited by N.C.G.S. §§ 14-269.3, 14-269.4, 14-277.2, or 120-
32.1. (school grounds, areas where alcohol is sold and consumed, state
property, legislative buildings, and public gatherings, such as parades);
2. any area prohibited by 18 USC § 922 or any other federal law;
3. any law enforcement agency or correctional facility;
4. a building housing only state or federal offices;
5. an office of the state or federal government that is not located in a building
exclusively occupied by the state or federal government;
6. a financial institution; or
7. any premises, except state owned rest areas or stops along the highways, where
notice that carrying a concealed handgun is prohibited by the posting of a
conspicuous notice, or statement by the person in legal possession or control
of the premises.
