Me?? Working in a dispensary?!?!

A few days ago I got into a really nice conversation about marijuana with a woman I met, and she told me that I should work in a dispensary (which I've always wanted to do!) Is there anyone out there that has/is working in a dispensary? Tell me about your experience! Did you have to be super knowledgeable about medical marijuana? What was your interview process like? Any tips you have for me????
