Some version of me and my wife.

Wife: "Which trousers should I keep?"
Me (pointing at a pair):"The blue ones look good!"
Wife: "That's green. Anyway, I'll keep the grey ones."

Arbitrarily forcing a choice to clarify your feelings on the matter can actually be very useful, it's just a bit rude to use other people for it. When I have a choice like this I'll sometimes throw some dice (d6, 1-3 for white, 4-6 for blue), if I'm happy or don't mind what they landed on then it's the correct choice, if I'm not I'll probably realize which option I was secretly hoping for and go with that.

My wife wants to paint our bedroom drawers, so got some testers and painted a small section on each drawer. She called me in and asked which I preferred.

I gave my answer.

"No, it's none of them," she replied, "None of them are any good"

I'm glad she asked my opinion.

Sometimes you need someone to remove the element of voice to actually realise if you feel comfortable with the pick.

Other times you want to know which would your buddy pick so if in the future they do pick that one, you don't have the same wearable.

Sometimes they are being a dick by implying that your taste sucks so whatever you pick is the one they shouldn't.

Being used as anti-picks is very real.
Similarly this runt.

I actually like this as a decision making tool.

Flip a coin, if the outcome truly doesn't matter, go with whatever it says. If you're disappointed with what the coin decided, go with the other one.

Ask, they said white, preferred they would have said blue, you now know you prefer the blue one.

Looked through the comments section. I had thought this was a joke about the stereotype of how gals don’t like wearing the same thing / be caught matching?

Classic Married With Children gag

Peggy asks Al which shoes he prefers, and goes with the other ones

Uh, 'hot take':

People who do this are inconsiderate assholes, in one way or another.
