“So you’re saying that you were afraid that this drunk person sitting in a chair and not making any attempts to approach you will actually kill you right then and there even though you were in a place you can only access through metal detectors and scanners so he was clearly unarmed, you were surrounded by other people and with security nearby? And even though you felt there’s clear and present danger you wanted to leave until you realize what his motives were? Ok, noted…”.

I mean, it might work, who knows. Would be interesting to see how this plays out.
