Tupperware came in a wide variety of convenient, space-efficient shapes and sizes. Maybe modern Chinese takeout also does? My experience is extremely limited.
Back in the day, extremely few people were regular consumers of any take-out which might come with free could-be-reused containers.
Vs. these days, not filling the landfills and oceans with cheap plastic take-out containers is a thing for quite a few people.
I keep wishing I could find a chinese restaurant near me that still uses oyster pails for everything, and solves the leakage issue by just not gooping up their food with so much sugar syrup that it becomes a problem in the first place.
But I suppose people around here gotta have their General Tso's.
