Triple retail at restaurants, for alcohol, has been a thing for decades. They always claim that it involves the server delivering it, the barkeep ( or sommelier if they have one) providing it, and the dishwashers having to clean the glassware.
But yes, paying $45 for a bottle of wine that retails for $15 ( bourbon in your case) is nuts, but we do it.
Kinda’ like paying for season tickets for a sports team that delivers a mediocre product.
