Going to this specifically:
I'm not going to justify my attitude or anything else, but this was the point in what I was trying to make. Got it, it holds batteries, therefore "Battery holder".
The reason it made me a little curious and kind of chipped at me was just due to the fact that she works in a shop and has never seen a mod with a digital display before? Yet they sell the Innokin iTaste MVP series. Odd isn't it? Overall, the point I was making was you don't work for a business and not know what you're selling, or be somewhat of the 'subject matter expert' (SME) of the other items that may walk into your store. That would be like me trying to sell and repair TV's and not know a damn thing about the brand, manufacturing process, parts, accessories, etc of every possible brand of television that walked through my door. Not to mention you had to be there to hear HOW it was said as well. I think that's why the other salespeople that were in there were kind of thrown back and she was quickly moved off the sales floor. Again, am I justifying my blunt and straightforward response? No, I'm clarifying what my post was intended to be about. Knowledge of your products and various other products out and about. Again, other than that, pretty good store to stop into. The rest of the folks there have a pretty vast knowledge of their equipment both in and out of the store. They were also pretty helpful as well. And yes, I did ask them a lot of questions, they did answer them in a professional manner, and if they didn't know they said "We really don't know". Which to me is an acceptable answer. Would I have did the same thing with any other device? Absolutely.
Now back to my hole... ah but before I go - needed to mention - my wife wanted to see what all the craze was about, why I've been spending copious amounts of time in my "den" and what I've been brewing up. She's smoked back in her teen years and just didn't like it, she's smoked hookahs with me in the past and loved it, although it gave her a headache from time to time. So she wanted to taste some of that "flavored air", which is what she calls it, and I was cool with that. Now she's content and she's having a blast. I told her I would eventually get her an RBA / RDA so she could build her own stuff, even show her how to do it. Or direct her in the right direction to get it done. She wrapped her first coil, made her first atomizer setup, and told me it was frustrating at first but she had fun doing it. And she'd gladly do it again.
