one day at the va smoking area, a macho guy who said... Within my ear shot... That (paraphrasing) 
vaping was for whimps who couldn't handle the "real thing" (smoking) got my attention.  He was a complete stranger but  i couldn't resist.... Had a pv loaded with 36mg nic in my purse... Pulled it out, put a clean drip tip on it and cranked it up to 10 watts before i approached him with "oh, really, then you won't have a problem trying it... Right?"  he had to take my challenge as he was being a blow hard in front of half-dozen other guys.... Bwahahahah.... Just evil i know but when he got 
through choking/coughing he handed my pv back without another word and i returned to my quiet corner equally silent but with a smile.
