Gut reaction: “oh it’s just undeclared milk, the milk itself is fine, I’m not allergic to dairy so no harm no foul”.

Problem with that is, some people are allergic to dairy, and/or are lactose intolerant, so it’s essentially poisonous to them. We gotta stop, as a people, thinking of people with allergies as a problem or inconvenience. It’s rather that certain substances are fine for most people but are toxic to some. So those things absolutely need to be declared. As one who is allergic to peanuts, I prefer to buy products from companies that not only do not use peanuts, but have declared themselves a nut-free facility. (I wonder how far that extends. Like, if you work there, can you eat peanuts on your break? Maybe that’s fine but they cannot come onto the production floor.) The Tootsie Roll company is one. Pretty sure the company that makes Andes Mints is another, and Andes Mints are, hands down, the best candy anyway.

Who would even dare buy food there?
