They were (and are) a huge mistake. Not everyone knows that these Biscoff cookies contain cinnamon! A large number of people dislike cinnamon, and most sources of it contain heavy metals. There's also some early research to show that it causes cancer, although the quantities in one cookie are likely not going to hurt you as much as the radiation from the plane you're on.

Hope they get rid of these, it's always a hard pass for me, and I've seen so many others just skip or bin them after one bit.
