I just ordered the Blu as my first, and was explaining to my manager ( i work at wal-mart, and I get chewed out for smoking outside in our "corall", a part of our garden center separate from the main building where we load softener salt and mulch and whatnot, because we're not supposed to smoke on the clock and they're just as anti-smokeless tobacco) and I got the reaction i expected: not on the clock. Which trips me out as every single one of my manager's smokes. i also fully expect to not be able to get away with it as a customer as I can be reprimanded for things occurring on my time as well. Flippin wal-mart.
You may not want to test the waters but you could always ghost vape. I don't know how much you know yet but ghost vaping is just holding in the vapor until there is nothing when you exhale. You can also get something like an eraser topper to cover the LED and no one will even suspect what it is.
