I'm not entirely opposed to the idea, however as a business owner I would probably impose some serious restrictions. For instance: you can go to the range and shoot, but once you enter the bar your hand gets stamped and you can't return to the range that day. The bar stuff then would be the normal stuff: don't over serve people.
But yeah: the idiots at the range can be scary enough, I really don't want them liqoured up too.
That I would be okay with.
