The money aspect to this is the least relevant I feel.
Like in my own case if we go out for dinner whether my partners meal costs $20 or $100 doesn't really matter.
What does matter is the cringe. I would just feel so awkward when every other diner order's like "I'll start with the quail eggs and then the crab noodles for my main course" but my partner is like "right, ok, so, does do you have a gluten free option for the crab noodles? ... "
