I've never owned a microwave, instead I air-fry everything. Pretty sure this is the same trick restaurants use, especially fast-food ones. Microwaves make soggy leftovers.
Microwaves work pretty well for saucy Chinese food, for example. (The alternate method is usually steaming, which is even soggier.)
But the warmth in the food heated on a burner is nicer than the warmth generated by the microwave (more even, cools slowly).
Maybe we slow down and expect our lunch to take 10 minutes to heat and 5 minutes to clean up?
