Would I ever recommend a mechanical and a dripper to someone new to the hobby? Of course not.
But let's be honest a person doesn't just walk into a vape shop and ask for a dripper and a mechanical, usually these people walk in with the intention of buying it to make big clouds. Usually they've seen it on YouTube and they want to blow the big puffy clouds. Now a vape shop has to make a rational decision, do they sell this person an item they want knowing they're new? Or opt to say no and lose this person as a customer forever when he finds out they won't do it? In some cases you can steer the person in the right direction but everybody I've ever seen at my local shop that's new and comes in asking for this stuff comes in knowing they want the big puffy clouds. I can't blame the vape shop either way really, unless it's the shop forcing the gear on the person which I've never seen... and I hope it doesn't ever go down that way, but if it does shame on you. But if they ask for that setup and they're over 18 what can you do, say no? That's a potential customer you will have lost forever.
