It's rude not to respect the wishes of a partner.
Bob asks his wife Cindy not to go to a specific business because they ripped him off 20 years ago.
Cindy wants to find a good deal on a product.
Cindy avoids the store since the wish may be irrational, but she'd want him to listen to her if she'd done the same.
Cindy finds that deal in the very store Bob banned her from, deciding since the request is irrational that she need not obey.
Cindy settles for the second-best deal in town when buying this specific product.
Bob finds out, and he's furious, and they get into a big argument.
