I don't know which is worse, McDonalds or Golden Corral. All I ever see at GC, are people that tip the scales at 350+, going back to the feeding trough, for another plate full. I don't go to either place.
My brother used to donate plasma at a Bio-Life. One time, before donating, he stopped at a McDonalds and ate a Big Mac, fries and a Coke. After the blood draw, the technician asked if he'd recently ate and showed him the vile with his blood and floating bubbles of grease. He doesn't eat there any more!
