I dunno. It's so hard to get a plain ordinary brewed coffee at Dunkin these days, the kind of coffee I used to get there back in the 1980s. On the app I could actually pick one out, in person I'm likely to have a teenager give me something else and then have a nervous breakdown when I point out the one thing I care about on their digital signs: "If we get your order wrong we'll re-do it"
I pretty much exclusively drink black coffee or plain espresso and I’ve yet to encounter any issues getting it.
I have seen lots of complaints and memes to this effect, but never has it been my lived experience. I’ve also never had an issue with politely saying “excuse me, I actually ordered X and I got Y by mistake.” No nervous breakdown at all
Dunkin' was taken over by the cheese mafia. Over half of their products now have cheese in them.
(Starbucks, too. They just discontinued the little protein box with hard-boiled eggs in favor of yet another one with cheese.)
