Why is impossible to find Borden chocolate milk In houston gas stations?

I’ve just about had it with this crap, all I ever see is that other crappy chocolate milk, like where bloody hell has the Borden chocolate milk gone off to? I just want me milk.

Pretty much have to go to shimpleys donuts to get this chocolate milk. The only gas station I’ve seen it at recently is on 610 and Durham.

Does anyone know why they’ve done away with it?
