mods aint for the faint of heart, you need to know what you are doing.
Walking into a B&M with arguably the best regulated APV on the market, and being dissed, is entirely wrong.
I sport a Vamo. It's not sexy, it's doing a job though. The least I would expect is for them to do -their job- and serve me, not diss me.
I'd have been furious.
Sub ohm is not for everyone, and certainly shouldn't be considered a goal, unless you set yourself that particular goal. I have no issues with sub ohm, and will probably dabble with it when -I- feel confident I'll know what I'm doing. To be dissed for not doing it is pretty unprofessional.

When they get a grip, maybe they will still be trading (hopefully). I'd not go back until attitudes have been seriously adjusted however.
