Tl;dr: 75-yo old woman attacks the employees over a sandwich, rips hair from one of them, put that hair in her purse, calls the police and dies.
At that point, two other employees intervened, and as they were pulled apart, a “chunk of hair” was pulled from the shift lead’s head, “leaving a raw area.”
Once separated, the employees got behind the counter and Grayson sat down, taking a phone call. She was seen picking up the shift lead’s hair and putting it in her bag, police said.



That in matters of taste bit was added recently, started circulating on tiktok. There’s no evidence of it being part of the original saying.
I’ve been hearing that since the early 2000s at least. So if it is wrong the origin isn’t tiktok.
I had to look this up.
In short, point to you for your correctness on the origin.
