Most of the time, if-when this sort of thing comes up I'd prefer we each go and do our own thing (you go for tacos, I'm going for a burger), and meet up again later. That way, everyone ends up happy - and fed.What do you do when you have a disagreement with someone about what should be done in the real world? For example, your friend wants to go to a certain taco restaurant for lunch, but you're feeling teriyaki today, and you can't go to both places. Perhaps, if the disagreement is simply too great, you just don't go to lunch at all, which I hope you'd agree is rather a shame. More likely, one or the other of you shrugs, saying, "Sure, we can do that this time, but next time you're taking me to X." Likewise any other aspect of doing things together with others: what games to play, what movies or shows to watch, what team name to use, what music to listen to...you find some way to build consensus.
I mean, would you say you struggle to resolve situations like disagreeing with your spouse/SO/best friend/roommate/etc. about which of two mutually-exclusive things you want to do?

With a typical RPG group, however, there's two other issues. First is that there's almost always more than two people involved, meaning you can end up with multi-way or multi-option disagreements rather than just a yes-no. Second is that the specific intent is that it be a group activity (as opposed to eating lunch, which most people can do quite well on their own), which somewhat forces more surface-level agreement.
