i've noticed this thing about smokers. if you're not smoking a "real" cig, they feel as if you're deprived in some way and out of the goodness of their hearts they really really want to share with you the "genuine experience" of smoking a cig.
i noticed this when i hand rolled my own smokes (and preferred them this way), and it holds true when someone sees that you are vaping.
when i first started vaping i would accept these cigarettes, just cuz. the last one i accepted was in dec when i was at a work xmas party and one of my vision clearomizers decided to disarticulate when i was walking on my way there. i couldn't even finish the damn thing, and i felt pretty terrible. i also accepted a cheap low grade cig my mom likes, which i hated even when i was smoking tailor mades, when i was enduring a trip to the apple store. i wasn't yet accustomed to my current power outlets, and didn't realize that my 650 mah batts were only charging for about 5 mins of use. they were randomly dying and i didn't want to "embarrass myself" by vaping a dying device with the smokers. seriously. from the lingering smell my clothes, hands, hair, and breath i swore i would never touch another cigarette again. mission accomplished.
whenever i'm hanging outside my venue/bar vaping and someone offers me a cig, i just let them know they don't realize how yucky it is til they've tried vaping for a while.
ugh.
