The difference between Coca Cola and Arbys is, Coke is a cultural icon. Arbys is a warning sign for crap ahead.
Roy Rogers defined the standard for fast food roast beef. It was good.
As far as your ruminating about spitting in people’s food, I’d ask you to grow up but even I have realistic expectations.
Then again, the threat to have your food spit on by a simpleton moron only reaffirms my assertion that Arbys stands for "Crap ahead."
Your mileage may vary, but not by much apparently.
