He might have been counting occurrences of drinking a beer, not total quantity.
Buying soft drink in 2 liter bottles is usually more economical than buying a case of 12oz cans. However, the 2 liters usually “go flat” before one person will finish drinking them. Therefore I buy the case, knowing full well that the price per ounce is higher than that of a 2 liter bottle.
Your Redneck may have been operating on the same assumptions, just unable to articulate his reasoning to you.
BTW, I am a white boy of rural Georgia ethnicity.

As far as soft drinks, I keep several rinsed smaller plastic bottles on hand, 12 ounce and 1 liter, and purchase the much less expensive 2 liter store brand sodas, especially when on sale. Upon opening a chilled 2 liter bottle, I transfer the contents into the smaller bottles discarding the 2 liter plastic bottle. Then drink as desired.
This allows me to purchase at less expense and avoid flat carbonated soft drinks. And even if a partial smaller bottle goes flat, all that is necessary is to top it off from a fresh 2 liter bottle. After all, the ingredients are still good, you just need the fizz.
So paying attention to price and product plus controlling portions can save you significant money with no compromise in quality. Sadly, today's math-ignorant kids are not capable of the simple calculations leading to these money-saving techniques.
