Sounds like a huge waste of money on top of the risk of reckless driving. At a buck apiece for, say, a nip of Southern Comfort, they're spending $35 instead of $20-$25 for the whole regular sized bottle.

That's the kind of nickel and diming false economy that one of my cousin's ex-husbands indulged in that drove them into bankruptcy. Instead of buying a carton of cigarettes at payday he'd buy a pack a day at almost double the cost. On top of that the bank charged them per use of the debit card, regardless of the amount. So he was running up their bank charges ten times or more the amount he'd have paid buying a carton at a time. And no matter how often they ran short of money he never learned, never stopped doing it. He convinced himself he was spending less money because it was only a little at a time, bleeding them dry drop by drop.

I see folks at the corner convenience stores doing even worse, paying a dollar apiece for a single cigarette at a time, or one of those wood, paper and poison things they call "cigarillos".

That's the sort of thing that could drive a person to drink.
