Legend
Why the newsprint? is it a tradition of some sort? British roots?
Probably from Britain idk. The food idea definitely comes from Britain. Most do Chinese though as well and some have Cambodian/Indonesian options.
Mostly because it's cheap I suspect they used to use newspapers but now it's plain paper. When I was a kid you could get ink on your fingers. Added bonus if you got the page with cartoons.
Some places use bags or whatever but most use newsprint. Also keeps the food hot.
You get a parcel to unwrap it too into. Inside has different paper lining and you pour the sauce into the paper. Wrap everything up when you're done and throw it out.
Cheap and convenient I suspect.
