First you have to have frozen chicken nuggets on hand at home. That means that you've already been to the grocery store, picked some up, and brought them home somehow to be stored.
Now you've also got a working and clean air fryer, sink, utensils, and other kitchen accoutrements that can be used on the nuggets. You may also find it necessary to have, on-hand, some condiments or side dishes to make a complete meal of the nuggets you're trying to make.
Then you put them onto a plate -- hope you got a plate -- and eat them with clean utensils, and then you clean that stuff up, wipe the counter, wash and put away dishes. Then you make a note on your shopping list or inventory, to replenish what you just ate.
It's not a simple proposition, all of these steps, especially when someone is a bachelor, mentally ill, isolated, etc. You feel it's easier for you, that is great, you've got some life skills, but other people struggle mightily with just the cleanup bits, for example.
