Purple spots in my burger

I sent someone to buy me a bigmac meal at mcdonalds lenasia trade route.after a few bits i realize there where 3 purple spots on the pattie.i was disgusted and threw the food away without even taking a picture of the disgust.i was to far to take it back nor did i have a slip since i had sent someone.This mcdonalds is notorious for ******* since their service especially at night is ****.they only take seriously other races and disregard black customers
