Was out for dinner this evening at a very large "tiki" style restaurant down here in the Keys. I was vaping discreetly, not blowing huge clouds around and I didn't think anyone even noticed. I usually use my MVP out and about, but I happened to be using my (very indiscreet) Tesla with a protank who's coil was getting wonky so I could keep an eye on the resistance (slowly climbed all day from 2.5 to 3.2). I set it on the table while I was fishing for my wallet, and the server apparently knew what it was. When he came to collect our bill, that was his exact quote. I don't see many vapers down here, but apparently the waitstaff is well versed in what they are.
