Well, I don't have a facility. I have a couple of rooms in the basement of my HOME. I'm not the only person living there, my wife and sons live there too and it's also their home. They have the right not to be intruded upon by strangers buying snakes.
Basically the only way you're going to be invited into my home to buy or even look at snakes is if you're a member of my family or a close enough friend to be on my Christmas card list.
If McDonalds knew how many snakes I've sold in their parking lots, they'd probably demand royalties.
I have a friend of mine who actually had a news crew show up on his front lawn wanting to interview him as the president of the venomous snake society and wanted to see all the venomous snakes he was keeping in his home. He had been turned in to a news station by a 'friend' he'd had a falling out with. Needless to say He doesn't invite ANYBODY over to see his collection anymore.
