Hated onions causes McBlow-up

Adam Mayer/KHQ ferretted this one out from Kellogg Police Department Facebook page:

“Called to McDonalds for a disgruntled customer. Apparently, this customer had a real hatred for onions. When McDonalds put the hated onions on his sandwich, he became upset and threw the McScrew-up at the front window. Manager obtained his license plate and K77 went to his residence to have a chat with him. K77 gave him a lesson in conflict resolution and deductive resonating skills and cleared. Peace restored.”

Question: Do you like onions on you hamburger?
