Walking into a typical gun decent sized gun shop, I expect to see lots of Smith and Wessons on sale (hmmmmm, wonder what that's about!?), plenty of 1911 clones, shotguns of all stripes, lots of varmint/bolt guns, 3 M1a variants, 5 AR's, 2 defensive shotguns (mossy 590's), a few Handi-rifles, 10 or 12 lever actions, a sprinkling of .22's and 1 AK.
Off to the side, I expect to see 5 or 6 cruddy condition milsurps that are more than a perfect example of one might be priced, and some used guns in a rack of various makes.
I expect to see 3 fat guys in suspenders (per visit), one crotchedy patron with bad attitude, 2.5 SKS commandos and or gangsta wannabe's oggling cheapo guns, 1 smelly guy, and one normal person (hopefully me).
I'm never disappointed with these expectations.
