I was in a Vietnamese restaurant near Santa Rosa CA this weekend, and I had set my Ba Gua on the table. I hadn't taken any hits off it inside, I just set it on the table to keep it upright. The first thing the waitress said, before "hello", or asking what I wanted to drink, was, "What's that!?" all smiles. I explained what it was and demoed it for her. She said, "wow, smells great!". I had five pawns Gambit in it at the time. I didn't continue vaping in the restaurant, but only because I was busy eating, and I do believe in common courtesy. It would have been perfectly fine to do so in that particular restaurant, I think.
