IANAL, but it seems possible that intentionally or negligently selling someone a product that definitely isn't what they thought they were buying could constitute something like fraud or misrepresentation. They might be liable for the cost of the hamburger, at least, because you did not get what you paid for. I also wonder if there might be punitive damages. Here's a random example of a case where there were punitive damages for a business-to-business negligent misrepresentation case: http://www.obrlaw.com/commercial-litigation.php?Third-Circuit-Affirms-5-Million-Punitive-Damages-Award-in-Negligent-Misrepresentation-Case-12 http://www.obrlaw.com/commercial-litigation.php?Third-Circui... And I'd also wonder if there could be something like pain and suffering or emotional distress. I doubt it would work to demonstrate actual harm (health effects, etc.) in unwittingly/unwillingly eating meat, but I think it'd be pretty easy to argue that someone might feel a lot of distress from being forced to experience something they have deeply-held beliefs against.
