This isn’t referring to hot cups that used to be styrofoam. This is about the clear plastic iced cups. Have you actually seen what they’re using that OP is referring to? Lately it’s been a generic paper cup you’d see soda fountain soda in, with no Dunkin logos at all. https://i.imgur.com/6suUTxd.jpg

Edit: took my name off the cup lol

Honestly I think it’s supply issues - the one I go to recently switched back to the normal iced cups after being generic for a few weeks.

Edit: again, this isn’t about the styrofoam change or about hot cups at all. It’s about the iced cups being a generic cup with no Dunkin logos at all. https://i.imgur.com/JvSb3iy.jpg
