"extreme worst case scenario"
exhibit c:
"almost a dollar"
waaaay ahead of the gotchas and objections my dude.
Additional space isn't an overhead rolling operating cost, and per unit is probably infestisimal. Additional man hours is a weird objection, do starbucks even track for "reaching for a carton slightly further away"? I imagine the time savings for moving a carton 4" closer are measured in the thousandths of seconds
oat milk has a longer shelf life (6 months) than cow milk (5 days) and when opened too (10 days vs 2)
The price doesn't have to strike you as reasonable or not because we are discussing whether we think starbucks are making a profit on oat milk or not. To me it's obvious they are making more of a margin on oat over dairy, whether or not that is good/bad, reasonable/unreasonable, fair/unfair is an entirely different conversation
