In typical Swifty fashion, the ad is also full of easter eggs to Taylor's life and music.
In a close-up of the receipt, the bill amount shows $19.89 — the year she was born, as well as the name of her 5th album.
There's also a charge for $13.13 (Tay's favourite number), the word 'Lover' (the name of her 7th album) and a drawing of a cat.
Other eagle-eyed fans have pointed out that there's plenty of 4's throughout the video — a nod to the 4th song on Lover, perhaps?
Of course, some could say that the ad is a huge easter egg in itself, with the diner theme alluding to her cameo in Katy Perry's video 'You Need To Calm Down'
Could another collab with her former-nemesis be on the cards?
