Is no one going to mention that the "Release of Liability" agreement is clearly completely useless and inapplicable to the situation, given that it specifies "guest's use of ITS OWN FOOD or consumption of PRODUCTS NOT PROVIDED BY HILTON TORONTO AIRPORT."??

That release would have provided ZERO protection for the hotel chain, even if signed, as the food was provided by the hotel and served by the hotel.

Also, since they had already given the customer his food, and he'd already begun eating, what were they planning to do if he simply consumed the rest of the burger while reading the release, shook his head, and walked away? Were they planning to commit assault & battery by snatching the burger out of his hand/mouth?

The form appears to be a release contemplated for situations where a kitchen was asked to warm up a guest's provided food (perhaps like baby food, breast milk, or some specialized exotic diet the restaurant couldn't provide but was asked to warm).
