They’re talking about bubble foam tea. Sure that was a thing but at least in any part of America I’ve been in, boba tea and bubble tea from the start was the tapioca pearl drink.
Some people get this purist notion that things can only ever be one thing and screech if someone uses a term differently.
I can (potentially) explain the double bagged paper. Growing up in the South that was the de-facto cooling rack, no wire racks or wax paper like you see today. They were cut open, laid on any flat surface, them cookies or cakes or what have you were laid on them to cool. They’d wick away moisture or grease and be easy clean up.
Free with groceries and if they were double bagged you had enough for a double batch of chocolate chip cookies while also usually guaranteeing (usually) the bag wouldn’t split from condensation or something before you got home.
