I’ve heard this is a good analogue to dementia. When you list out all 14 steps of making coffee, it’s not surprising that someone with an impairment gets things wrong.
Note that you didn’t specify where the pot and coffee maker are, how exactly to measure the coffee, where the filter is, what to do with it, exactly.

Toll. Genau die demographische Gruppe – die einzige –, die vielleicht ab und zu mal darauf angewiesen ist, dass ein Lineal richtig misst, kriegt den Ramsch weiter.
