One restaurant worker was killed and another was wounded after a man opened fire after arguing with them about the amount of mayonnaise they put on his sandwich, authorities say. Brittany Macon, 26, was working at an Atlanta-area Subway sandwich shop on Sunday evening when a customer became angry that his sandwich wasn’t the way he wanted it. “Believe it or not, it was about too much mayonnaise on his sandwich,” store owner Willie Glenn told Fox 5 Atlanta. “”He decided to escalate the situation and from there, and that’s when all hell broke loose.”
