As soon as you see the sign "'Normal' people need not (actually four underlines) apply," you know Ten Inch Hero is not going to take place in your everyday beach grill. It's much more like an imaginary beach grill, taking place in the mind of a film school's saddest Kevin Smith fanatic.
Someone must have honestly thought, "Why is there no movie with, you know, real people like us, doing stuff, working our shitty jobs, but mixed with horrible sexual innuendo and the ham-handed melodrama of a CW program? Also, I somehow missed Empire Records and all the movies that are already like this but better."
If this all somehow appeals to you--maybe because of the zany, outdated punk character and his never-ending stream of novelty shirts, maybe just the claim that "at this funky sandwich shop... love is a special order"--I'm afraid you won't find it in theaters. Or even on DVD. This point of this trailer is to spark enough interest that someone, anyone, will take pity and release this in any way. Very telling.
