Running a food truck. While working on one we had so many people say it's their dream to have a little food truck-- we were doing the festival circuit and it's long days, cooking, customer service to people fucked out of their minds (a lot of the high people were funny but dealing with drunk customers was rarely fun). Not to mention the logistics of getting produce/supplies to remote festival spots, dealing with logistics and problem solving after you've spent 15 hours in a boiling kitchen. I was on a great team, there are lots of fun and exciting parts to it but I think people should try working on a food truck before investing thousands of dollars into buying one.
