When the camera cuts to Daenerys sipping the wine, social media users were quick to point out to an item that was out of place. A cup from out of the realm appeared to be sitting on the table: a Starbucks cup that had been left while the scene was being prepped.

"You're telling me they had TWO YEARS to put together a decent show and they couldn't even spot the g—n Starbucks cup in Winterfell??!?! #GameOfThrones," one user wrote. Others agreed:
