Canada

First, the waiver should have been provided prior to serving the meal.

Second, and off topic, Toronto Pearson area seems fraught with problems. From second-hand experience of a family member, they got delayed by 11 hours after the 3 hour layover, simply because the airport apparently doesn’t know what electric surge protection is (that was their excuse, that a surge occurred in the airport grounding their plane).

Last, anyone who wants less-than-well-done meat should expect a semblance of risk and expect the restaurant will want to legally protect themselves. But it’s pretty shitty to get the waiver after being served.

So as a throwback to the AITA subreddit…ESH.
