I work for a gov. health authority in an "open office" concept. My director and team I work with all know what I'm doing and have no issue with me vaping freely at my desk (in fact a couple of the guys dig my little gizmos and have asked why mine don't make the plume of smoke like the mall rats, I tell them it's the cheap chinese juice they use that's full of chemicals, they bought it
It does take a bit of practice but now it's just become automatic, it's taken a while but now I personally find it every bit as satisfying as normal vaping...to the point where I find myself doing it at home and in my truck...only issue now is that the Derringers tend to be a loud RDA for snap/crackle/pop, which is why I like to sink them...it quiets them down considerably.
I vape everywhere, including a trans-con Lufthansa flight to Amsterdam...in carry on luggage 3-4 batts in a ziplock with some duracels, the mod just chucked in with a change of clothes, juice bottle in a ziplock with my mouthwash/toothpaste/etc. and the RDA is tossed in with my wifes cosmetics/tweesers/etc., board plane, seatbelt sign off, re-assemble and enjoy
I really want to beat the mall rats about the head with their own tubes mods...they are seriously screwing the rest of us.
