I know this is a bit "nicer problems to have," sorry. It's also light-hearted!
We have two bathrooms: the 'main' one and an ensuite off the master bedroom. Both bathrooms have a toilet, sink and shower. The main bathroom has more space, plus a bath.
We have young children, so mornings involve nursery/preschool run, and we also have a young baby. DH is getting ready for work at the same time.
The issue is that DH keeps using the shower in the main bathroom, or going for a poo, just when the rest of us all need to be in and out, using the toilet, washing hands and face after breakfast, brushing teeth. It's about 50:50 whether he uses the main bathroom or ensuite and his choice seems to be completely random 🤣
He says it's not a big deal; if he's in the main one, anyone else can just use the other one. But my argument is that the 'main' bathroom has more space for multiple people (because I have to help the little ones with some things), and all the equipment is already there (kids' toilet seat, kids' step, toothbrushes, etc). I'd have to nip in and get the stuff, and we're trying (!) to teach the little ones about privacy, so that's not ideal!
So wise MNers, who is BU?
YABU: It's no big deal, if he's in one bathroom just use the other one
YANBU: If he's going to be in there for longer than 5 minutes he should use the ensuite
