I have no unloaded firearms in the house, my holster or my car. Even if they're unloaded.
Maybe it's just me, but it seems every 'professional' I know but one is lax on firearm safety. Not sure if it's the macho factor, the over familiarity factor or the show off factor. They never check the firearm before trying to hand it to me, never check it after I check it and hand I to them, cover wide swaths of the room with the barrel, etc.
