John does not have the right to sue Susan for standing him up. The only thing Rosalie did was invite him to dinner, which he accepted. I think a dinner invitation is an agreement, not a legally binding contract. There is nothing binding this invitation to dinner. The purchases that John made in eagerness of the dinner was a choice. She didn’t ask him to purchase these items when she extended the dinner invitation. If Susan would have asked him to purchase the extra items for dinner, and he agreed to it, there is a possibility that he has the right to sue, because it’s a verbal contract. But since this isn’t the case and if he still has the receipts, he can return the blazer and shoes; personally, I would keep the champagne.
