'Game of Thrones' Flub: Jaime Lannister Brought Coffee to Joffrey's Purple Wedding! PHOTO

Someone forgot that Game of Thrones is supposed to set in mediaeval times and anything modern seems out of place. After noticing this little flub on set, it makes you wonder if they had coffee shops somewhere in Westeroes.

According to Uproxx, a meticulous fan spotted a little mistake during the rehearsal footage. If you play close attention, you'll be able to see noticeable item that shouldn't be there. In the group shot, Jaime Lannister (Nikolaj Coster-WaldauI) is actually holding a paper coffee cup in his right hand.

This is rehearsal footage, where everyone has learned their lines and is wearing the right wardrobe. There's obviously someone who's keeping track on continuity but that person was probably sleeping on the job. How could they miss something so blatantly out of place?

As Jamie Lannister, Coster-Waldau also forgot to bring in his golden hand prosthetic. Did Coster-Waldau forget to throw away his paper cup or was that a damn good cup of coffee? Or was he actually trying to hide his goof behind the kid standing next to him?

Check out the photo of Jamie Lannister holding his coffee cup:
