For us it depends on what we're doing. For things nobody wants to do (chores) we have a list of designated chores everybody has. Sometimes it simple stuff like shower, other times it's laundry and grocery shopping. If you just mean like going to a restaurant and ordering food though then I don't have many tips for that XD Usually the way we do it is whoever is fronting at that moment gets to decide. Sort of like whoever's driving gets to choose the music type deal.

To be honest we struggle with this too, how we combat it is by having a reward set up for whoever does the chore
