Well Bushmaster coulda had legitimate business in there. He may be a plumber. The gunshop coulda had a stopped up sewer. Bushmaster, through no fault of his own, was obligated by the Hippoplumbic oath to relieve the suffering of the poor store owner. And then the gun peddler strong armed him.
Or he could have been delivering pizzas. Same thing. Or he might have been asking for directions. Stan you are too quick to judge.
Or, he coulda' been killing time while his wife was at a Drs. appointment. Yeah. I've been through all those excuses myself, too. I remember well walking into a shop while my wife was at a Drs. appointment, just killing time mind you. Saw a Ruger No. 1 on the rack. Looked like an Alex Henry forearm on it. I asked, "What caliber is that, Joe?" He replied, ".45-70", and handed it to me. When I looked at the wood in the buttstock I said, "Oh, no." Joe grinned a big ol' grin, knowing I was a sucker for pretty wood. It's in my safe now. I sold a Ruger No. 3 in the same caliber and the No.1 stayed. Good short range deer and hog gun.
You just stepped onto a long and slippery slope, Bushmaster. Be advised, the cure is worse than the ailment. Enjoy it.
