Which of the following is NOT a reliable indicator of intoxication and should NOT, by itself, be used to refuse service?
Explanation
Accent (a) is not impairment — it is a feature of the patron's language background. Refusing service based on accent risks national-origin discrimination under the Unruh Civil Rights Act and California Civil Code §51. Servers must distinguish 'I can't easily understand this person' from 'this person is slurring.' Slurred speech (d), stumbling (b), and spilling (c) are objective SCAN-category signs that DO support refusal.
