Are you serious So after leaving the drive

Are you serious?!?!? So after leaving the drive thru today my wife took her sandwich out of the bag and we see THIS!! Seriously? Oh not today, not today!! I went back to the restaurant, went INSIDE (already fuming), asked to speak to the manager and then threw the sandwich on the counter. I asked him for an explanation. He looked confused, so I pointed at the writing on the sandwich and demanded that he tells me why someone felt the need to write it on my Wife’s sandwich. He answered, "because you ordered a BLT with cheese??” To which I replied “Oh” 😶
