Refusal at the door
Under licensing law, you must not admit someone visibly intoxicated. Refuse politely, direct to alternative transport, offer water where possible.
Extraction from the premises
Two-guard escort, minimum force, calm voice, no argument. Escort to the exit, not to the pavement — let them clear the immediate zone under their own power.
Medical red flags
Sudden unresponsiveness, uneven pupils, seizure activity, extreme temperature, difficulty breathing. Any one = 999 immediately. Assume it's medical until proven otherwise.
