Also a comic book shop employee in LA, at one of the most popular shops in the city.
I definitely NEVER have time to read comics. I meet tons of cool people, including many many creators. Sterling Gates visits frequently, as do some other guys. The creator of Butterfly came in yesterday and was thrilled we had copies of his book. He signed a bunch for us.
People wonder why we don't have smaller comics, its because you don't preorder them or tell us you want it. We don't order things if people aren't telling us to; its a business.
We have a few crazy people, for sure. The ones who'll talk your ear off when you are loaded with work to do. The ones who try to haggle prices with you. The absolute worst thing for me is people reading comics in the store. Flip through it, check it out. Don't read the entire thing. I had a guy read AN ENTIRE TRADE in the back, trying to be sneaky about it. Please don't.
I'll be honest, working at a comic store is NOT nearly as fun as you'd imagine. I am stressed more often than not, but its still rewarding enough. Still better than a fast food job!
