So, who wrote Pig?
If she/he didn’t do it, then she/he shouldn’t have been fired.
But what did the manager do afterwards? Give the cop a muffin and tell the person she hired don’t do that. If they wrote an insult to a black man or a transgender, I bet she and Starbucks would have fired them on the spot.
She didn’t write it but her management style probably allowed it to happen.
