Yeah, I'd agree with leaving it up to the establishment about smoking. That's certainly reasonable.
Sin Tax? More tax is a sin if ya ask me....... Pot smokers will argue that ammunition is a sin, so why are THEY being singled out.......and the next thing ya know, we'll be paying through the nose for ammo purchases....... and if you let them specify higher tax on something that's a "sin" they'll be able to regulate the amount that can be sold and to whom it can be sold to....... We're damn near there already.
