I was expedited out of a grocery store once. I was at the customer service area where they keep their liquor behind a swinging gate. It was my first time there. I asked her if I was allowed through the gate to find my etoh. The clerk looked at my gun and said, "No. What can I get for you?" She instantly went to fetch my bottle of Malibu Rum. The next time I went to that store she wasn't there and I saw that a customer had gone through the swinging gate. So I entered and got what I wanted.
(No, I'm not an alcoholic - yet.)
