The legality of the consumption doesn’t bother me near as much as pulling it out in the bar honestly.
I’ve had a number of people ask me over the years about what I’m carrying and if they could look at it and I just smile and say it’s an XYZ model/brand and say, sorry but no, I can’t legally draw it from the holster in public unless I’m going to use it in self defense.
Now, at a range, gun shop etc where it would be contextually appropriate different story but in a bar like that even if it were legal there’s really no completely safe way to do so and a million or so ways it could go very wrong, pretty well instantly.
I would consider that to be an incredibly irresponsible thing to do and anyone that irresponsible with a gun in their hands is a danger to me and everyone in the room
