Ohhh they do not do domestic very well! Let us assume that for these answers, they are cohabiting in the TARDIS as Ten and Simm!Master, and not trying to murder one another too often.
Who is the big spoon/little spoon: The Master does not spoon! The Doctor is perfectly willing to have snuggles and be the big spoon, though.
What is their favorite non-sexual activity: Saving and/or destroying civilizations!
Who uses all the hot water in the morning: The Doctor. He always apologizes, though!
What they order from take out: Ten is really fond of fish and chips! The Master much prefers the gourmet take out one can have on Alpha Centauri.
What is the most trivial thing they fight over: Who gets to pilot the TARDIS on any given day.
Who does most of the cleaning: The TARDIS herself, poor girl.
What has a season pass in their DVR: Mythbusters!
Who controls the netflix queue: The TARDIS does, but she makes sure to let both the Doctor and the Master think they're in charge of it.
Who calls up the super/landlord when the heat’s not working: The Doctor is the one who works on fixing the TARDIS when something breaks. And then the Master usually fixes it much better when the Doctor isn't looking.
Who steals the blankets: The Doctor. The Master is actually slightly too dignified to do it.
Who leaves their stuff around: The Doctor. EVERYWHERE.
Who remembers to buy the milk: Neither of them. The TARDIS tries to keep them in food, though.
Who remembers anniversaries: Both of them, but the Master pretends not to.
