I was at the DMV last week, with my provari and a Phiniac tank...I'd been there over 2 1/2 hours, and needed a vape....I've come to realize in my 60 years that if you ACT like you are doing something WRONG, you will be TREATED like you are doing something wrong...so, I just vape, like I wasn't doing anything wrong!!!..no problem...2 days later, the same place (I had to go back with my birth certificate because of Patriot Act)...and the same LONG WAIT....after 5 minutes of vaping, one of the clerks came running out..."Ma'am, there's NO SMOKING in here." ....."oh, no, I'm not SMOKING, Dearie! this is my Personal Vaporizer, see?" .... "Oh, I'm sorry!" She said as she scurried back to her desk....I think she assumed it was a medical device...Provari is BIG enough to BE a medical device...and....at MY age, that's POSSIBLE...she didn't ask any other questions...and I wasn't FIBBING...
