I personally don't care where anyone eats, but if a Jew/Muslim eats in a non-kosher/halal restaurant, they're already compromising...
Vegans are opposed to eating meat because of animal cruelty, so it is hypocritical for them to eat at a place where 99% of the menu is meat-based.
Kosher/halaal is just a specific requirement for preparing meat for consumption. There is nothing hypocritical about Jews/Muslims eating at a restaurant that also serves non-kosher/halaal meat because those restrictions don't apply to people of other religions.
On the other hand, I don't think it should be a big issue to eat some meat once in a while by mistake. The impact on the general cause is negligible.
(I can't remember if the impossible burger is vegan or not, but I remember that they don't cater to vegans)
This is kind of what I feared would happen when you take something that’s so similar to real meat and let fast food workers try to sort it out.
Get rich ?
Financial Punishment? It’s not going to put a dent in their revenue
Name and shame ? It’s happened
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-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.
If someone has a strong religious aversion to a product, why are they eating in a restaurant that serves that product? Furthermore, their religion dictates they only eat meats blessed by a cleric of their religion, last I checked non-halal or kosher restaurants aren't sourcing halal/kosher meats. And vegans aren't a protected religious group.

Just being protected and getting the wrong food at a restaurant doesn't necessarily follow that you've got legal recourse to do anything.
That wasn't part of your question.
Do you typically rely on others to read your mind, while asking questions?
