Everything involving food is screwed.
We have free refills (was rare until some time around the late '90s—see the '80s film Gleaming the Cube where there's a sign on a Pizza Hut in a scene near the end of the movie advertising a special on pitchers of soda, which probably seems weird to anyone used to just having their soda constantly topped off, or walking to the fountain and doing it themselves) so it's easy to thoughtlessly sip down three or four glasses of soda with a long meal, and to-go sizes at fast food joints have ballooned in size in the last 20 years or so, like, the medium sizes are often larger than what I'd have classified as a large before.
And yet in a sister thread about Deliveroo we have people talking about what a "game changer" the delivery services are, eating 2 takeout meals a day without really understanding what's in the food. People eat too much.
