It’s usually not that complex. If someone has a plate of chilaquiles with egg on it and I say I’m vegan I don’t think it’s hard to discern that I’m probably not going to eat it.
Egg is obvious if you know what the difference is between vegetarian and vegan in the first place, but I don’t think you can expect most people to be able to cook vegan food, even if they’re trying, and know the basic definition. I know enough non-obvious uses of animal products(like shellac on fruit), that I’d have no confidence in being able to avoid them all unless I grew everything myself.
