Well we have vending machines that sell fish bait here in AR.
Cricketts, redworms, nightcrawlers, wax worms, and whatever that worm is simialr to the wax worm is.
These are like the ones in a snack bar, with the refrigde , shelf dealie. ( Sandwiches , milk and such). Fisherman shows up in wee hours before bait shop opens, next to the soda maching, gets a soda , bait and ready to go. Even hooks, bobbers and such.
I understand the legal deaile ( don't like or agree) , but hey, seems like a great way to manage time and employee/customer service. If I want a box of ammo, and I know what I want, let me get it.
Allow the gun behind the counter to make a sale on a gun, keep an eye on range, whatever. Time mgmt, for both of us. Especially for once a fella is signed in. Needs a box of 22lr, 9mm, 38 spl, 45ACP. MOre popular ammo, ear plugs, small bottle of lube...sounds like a great idea to me.
Works for bait, sandwiches, sodas, popcorn, aspirin...
