i think it's a 3 shift operation. you get 2 shifts (8 hours each, back to back) running a line of treat A. during 3rd shift, they swap out a couple of critical components during the 3rd shift production line deep line (to meet HACCP / health standards) and run Treat B for two shifts. i'm sure the engineering team that figured out how a single production line floor can, over the course of a week, run 10+ product lines each with their own packaging and terminating in a frozen/frigerated truck for shipping are some real logistics wizards.

imagine if they were paid to come up with built environments, networks, and community support systems to prevent diabetes and heart disease.

EDIT: no chance i would buy an entire box, but i would 100% try a deep fried twinkie.
