So if the steak dinner in your stomach was just about "finished" processing and ready to pass to the next organ, what happens when a beer and a bowl of pretzels enters the mix? Does the stomach suddenly go "dammit man we were just about to move on! Now I've got to start all over again!" and start reprocessing? Or are the new food objects just left undigested and lumped in with the rest of the food clump that is passed on?

It's not a "I am completed with this package here you go there next stage knock yourself out" process.
It's a "chemicals are removed and passed on in various orders depending on how filled the digestive process already is" process.
You're not a first-in-first-out organism. Further, you'r e also not a fastest-in-fastest-through organism.
If your innards are not otherwise busy, you process liquid foodstuffs far faster than complex organic foodstuffs like high-fibre proteins. But that processing takes time for the more filling types of food you eat, at least in most cases. Pack your stomach with wagyu-steak fats and proteins, and it'll take a while for everything to sort itself out even if you gorf down an ice cream sundae afterwards.
