Before you knew it, your coworker was bitten by a customer. Worse yet, your bitten coworker was behaving very strangely. He began to groan, his eyes turned red, and rushed to bite other customers.

The crowd became chaotic, screaming and running wildly. That coworker turned to you, he rushed over to bite you. But before he could catch you, a bullet went through his head. A tall, dark-haired man stood in the distance with a gun, shouting:

"That was close. You might get killed without me."
