I’m a guy who just finished working on the Fourth of July at one of those pop-up fireworks stores. AMA!
I thought people might be interested in what goes on at those pop-up stores that are up for like a month or two and then go away. Proof: https://imgur.com/gallery/8AZt371
EDIT: Thanks for all the questions, everyone! It's getting late for me and I actually do have to work tomorrow at the store, so I'm going to end it here. I hope everyone had a happy Fourth of July!
