And actually, you might've been able to earn yourself some free items by helping them out. I was in a "similar" situation, and by similar I mean the store owners had just began to sell vape stuff and did not know anything past the blu ecigs. I educated them to the best of my abilities on popular items, how to rebuild, etc. I even donated 2 hours of my time to perform magic for them at their "Grand re-opening". I wasn't busy and I could see how happy they were to learn something they are diving into and spending their savings basically to start up. I ended up with tons of free stuff as payment. Deep down, I was just happy to help out fellow vapers.
