I don't have any dealings with Moochers. If I did, I would tell them to piss off, cause that kinda stuff really bothers me.
My girl vapes too (we made the switch together from analogs), and we share, but she prefers to "steady vape" different flavors than me. It's kinda cool because I get double the flavors to choose from when I want something different.
There are a couple of people I work with who still smoke and I carry extra hardware at all times so I offer them to my analog buddies every time I get a chance. I have already converted one from my office and another co-worker is starting to talk about getting his own gear, so while I may give away some juice, I wouldn't classify this as mooching since I am offering. Of course, I figure the larger my circle of fellow vapers, the better for me since they will presumably expand my flavor horizons and do some of my research on new gear as well.
Hard to believe how many posters here don't know anyone in the real world who vapes! I have gotten three going in a few months (two partial, one quit analogs altogether) just by showing and offering, and one of my "converts" is the reason why I tried Gandalf for the first time. Recruiting new vapers is a fun activity to me that pays handsome dividends!
