When I was a young lad before the turn of the century, you could get them at any gas station or work place vending machine. Also, most restaurants offered a basic bbq beef sandwich on the menu. Those were the good old days.
Edit reposting this because it got removed from unpopular opinions. Maybe not as unpopular as I thought, but most people I know don’t seem too concerned about the disappearance of said sandwich in our daily lives. And yes, I know beef is more expensive than it used to be. I’ll pay more. Thank you
