Waldo has a point. One of my buddies thought that he was fulfilling a life's dream when he got his FFL and opened a shop. Within a year he packed it in, because of all the crazies that slithered in under his door.
Some examples:
"Dude, can you tell me what I have to file down to make that auto?"
"Dude, I'm buyin' it for myself... not the guy in the 50's, gang colors and bandanna that pointed to it in the case and handed me the money!"
"Dude, where can I get a flamethrower for duck season.. yeah.. that's it... duck season."
"Dude, I can get that AR at the 'gunshow' for $300 New In Box!"
However I've also run across my share of dealers who've lost many sales because of their attitudes.
Examples:
"Naw boy, ya don'ts needs ya' an AR lower. How's about buyin' one a these here Jenning derringers?"
"Why would ya' want a 'Booooschmaster'? Heck, I can gets ya' these here Century AR's for the same price!"
"The Ruskies designed that there AR ta shoot .223 also!"
"Don't get no Remington rifle. Here's a fine Savage over there on the rack!"
