During the zombie shooting contest free-ranging zombies attack "Side Meat" in the ice cream truck. (36:33) "10K" shows mercy by shooting "Side Meat" right between the eyes. "Side Meat" slumps down dead while zombies continue to eat.

Murphy bit Wanamaker but after Wannamaker stumbles into the bar, he pulls his shirt collar to the side and you see the bite is on his shoulder, not the neck.
After Murphy bites Wannamaker, he pulls his head back and for just a second you can see blood around Murphy's mouth. In the next second, the blood is gone without Murphy doing anything.
While fighting with Wannamaker for his car key, Murphy suddenly goes into zombie mode and bites Wannamaker on the side of his neck, however, there is no blood on or around his mouth. Then, after hitting Wannamaker in the head with a rock, the side of his neck is clearly visible and there is no bite wound.
