I do not understand the reason for the inclusion of the words "in the vicinity". This bothers me. Why can we not say "that would give reasonable apprehension that the person is incapable and might endanger himself or herself or any other person"? We do not need to add the words "in the vicinity". People could go home and endanger someone in the home. I do not suggest that we ask bar staff to make this judgment but the point is that we do not want this to provide a loophole.
