Great story, @Colored Guy, and cool idea for a thread, @cltattooing.
I love the feel of a shop crushed with flash. I've been in a few shops that have next to no flash on the walls, and it always feels very odd to me--even elitist at times. Plus, there's something about seeing artists deal with walk-ins that I really like. The negotiation, the hustle (on both sides of the dummy rail), and the end result.
