You never lose that ability. Dive bar etiquette is like riding a bike. Don’t mouth off to anyone and if somebody looks at you funny, buy them a shot.
Oh NOW you tell me.
Make sure that you have easy access to your concealed piece, or stay the hell out of "dive bars".
I'm going to meet an old friend today at an old bar in a suspect neighborhood.
The bar is owned by an old dago pal from back in the 60s {and he still shows up almost daily}.
We will have a coupla beers and a bite to eat {the food is great so I'm not sure this qualifies as a dive}, but the area is not where I'd ever walk or drive, without a piece {or two}.
