Person A thinks that's what's been served for dinner (2 adults, 2 DC under 7) is what we're eating. End of. If you don't like it, you don't eat it, that's your choice. It's delicious and not "out there" or very unusual.
Person B thinks if you've never had it before, try it a little and then say you don't like it, it's ok for you to be made an alternative just for you, so you don't go hungry.
Who is BU?
For further info it's one of the DC refusing the food.
It's squash risotto with sage and pine nuts so quite "adult" depending on your perspective / diet.
And the replacement alternative was a ham and cheese wrap, no cooking involved.
