I've found online vendors to be a lot more knowledgeable AND affordable myself. Ebay can have some great deals, but be wary of unscrupulous sellers, as I have gotten fakes, AND an EMPTY envelope at one point, and was even accused of making it up! Out of the thousands I've spent and 100 percent feedback score, I would have certainly picked something better than a $12 pack of 510/ego adapters to make a false claim over, like the $400 8.9 Kindle HDX I had just recently purchased, ha! Anyways, you can have poor experiences anywhere, and everyone has to start somewhere. I see a bit of "My ____ is bigger then your...." going on, which I can understand to an extent with the money, time and energy people have invested in their gear, as I know I have! Also, like fast food shops, I see a CS position in a vape shop, which is still a relatively new and unheard of industry to many is going to mainly appeal to younger workers. Owners, especially those just starting up will be struggling to stay ahead of overhead and make a profit at first, especially in a community where it's not popular YET, is going to want to keep cost down by hiring younger and less experienced workers and OF COURSE train them to sell THEIR products or why sell them to begin with??
My only experience in the only brick and mortar shop I've been in, in Nebraska, which says a lot ha ha, wasn't the most memorable. The kid was a bit immature IMHO, preferring much more to talk about HIS OWN personal gear versus what they sell. He kept trying to sell me on their juice despite the fact that I'm very picky, and only buy from certain vendors what I know I like, and I just couldn't get past the idea of putting my mouth a cheap clearomizer even WITH a "condom" that God knows HOW MANY others had their mouth on, and I didn't have a dripper at that point. Still I get what he was trying to do, his JOB, which is to sell me something! Of course all of their prices out of their scant inventory were WAY over inflated, (they were really PROUD of their stuff!), but for goodwill's sake and backup, I bought a cheap, knockoff protank, and mini pro. For $10 each, which I guess isn't ALL that bad of a price, they actually perform pretty decent.
I'm just glad there ARE vape shops popping up, advertising, spreading the word, and getting people informed and into vaping! We ALL gotta start somewhere, on both sides, (suppliers/consumers), and I hope the vaping community can stick together as a whole and stand for a long time coming! Sorry your experiences in B and M's have put you off, but next time, as someone else suggested, try educating and informing the person across the counter who's not up to your standards in a non-threatening way, and they're likely to listen and take yoru suggestions to heart. Try and remember that some people like myself prefer an excellent tasting, satisfying vape no matter WHAT it comes from, versus cloud chasing, top of the line RDA's, mech mods and the like, and that we're all on the same team, yes? I think with that attitude you will definitely start to notice the more positive elements of your experiences versus being exasperated, as is true with anything in life I suppose! Best of luck to you as you continue on your vaping endeavors!
