Is this true in a Starbucks? Every order goes into the computer before it's made, whether via the app or at the register. Or are you referring to something else more specific, like performing and recording the individual steps in making a speciality coffee?
I'd literally forget how to make cold drinks vs hot drinks when I switched, like I'd never done it, until I got into a new flow, and everyone found this to be hilarious, since I'd already been a software person and it was a regression being there.
I took the job because I needed some money and to make social connections, but I mostly just wanted to see if I could do it, and I couldn't.
Since then, I've learned to give myself a bit of grace when switching contexts. If I have a day zoned in on one part of the code, and someone brings up something I worked on a month ago, I'll have to stall for time while I hydrate my cache again. This limitation is somewhat debilitating, since adult life depends on constantly being anxious about invisible obligations and other bullshit that simply aren't in my conscious mind unless I'm specifically grinding on them.
I had the exact same issue switching from bakery, to line, to register.
Everyone else seemed to have this "context switching superpower". I watched two peers (we were all in high-school) seemingly effortlessly go from line to register and back to line 3x within the same shift. I couldn't.
I could do all of the jobs and was (subjectively) the best on-the-line (real-time 3D Tetris + flavor), but I could only be good one-job-at-a-time.
Truth regarding combining this with social interactions. Though I've never done it, I suspect my anti-job would be a bartender.
In a truly transparent system, one worker could take the place of another one by knowing which steps of an order have been completed, but that's not how their ticketing system works--nor should it.
In practice, hand-offs are done to other workers only for specialized low-variance duties (register).
