Well, then, my ideal LHS would specialize in all things 1/144 scale.
All the kits would be 1/144, all the aftermarket products would be 1/144, and they'd carry all the tools and stuff that we micro-scalers need!
Oh, yeah, and there book selection would be second to none!
Oh, and if they didn't have something, they'd special order it for you and have it in stock by the very next day, at no extra charge!
Finally, every last employee there would be very knowledgeable, and friendly too! None of this,"Well, this the train department, you have to check with someone in Aircraft" BS. Every last employee would know every last square inch of the store!
Oh, and it'd be clean, and they wouldn't make fun of us RPGers! There'd be a LAN center in the back, and a second floor, which would have gaming tables so you could set up you dioramas(if you're a modeler) or your battlefieds(if you're a RPGer) right there! There'd be a snack bar and pizza parlor, soda fountains(with free refills!), and airbrush stations, that you'd rent time on, which would be stocked with every color of paint imaginable, and the very best airbrushes and compressors, so you could simply waltz on in, rent a booth, and airbrush away!!
And on the third floor, they'd sell PC and video games, and RPG minis and sourcebooks! Oh, and on the fourth floor(there would be an elevator, of course!) They'd have in stock all the other scales of models you could possibly want, plus aftermarket sets! Finally, on the fifth floor, would be the world's largest BONSAI SHOP!!!
Yeah, that'd be MY ideal LHS!!
(And if any of you were wondering, my stepdad and I are actually intending to make a store like this someday, we're gonna call it "Gamerville"! We should be opening by 2010 at the latest!)
