I just don't get that. It takes minutes. All done, kitchen clean and tidy. Nothing left undone.
I'm inclined to wash up as I go with stuff. Baking bowls and utensils washed while the food's in the oven, etc.,.
There's never really a lot of dishes to be done. Even when there's a crowd in, folks just muck in and the job's done by the time the kettle's on for a final cuppa or someone's opened another bottle.
I don't see it as a chore, it's just part of making food, and then setting things back to right.
As you say though, each to their own.
