A production bay on drink mixes starts out on lemonade, moving next to lime, then the orange, then the teas, and finally the horrid... Red Berry to end out the run, and then wash. That schedule prevents colors and flavors from co-mingling. Doing the wash at the end after red seems like you’re in a bloody slaughterhouse. Walls, ceilings, rainsuits, socks and shoes, all murder-red soaking wet. Then back to lemonade. Each run goes for at least a week.
At the potato chip place it is probably unsalted chips first followed by salted and so on down the line.
But they either mixed up the flavoring hoppers or someone was totally illiterate. Maybe both come to think of it.
