Sample Zombies are the mindless creatures that derive their primary sustenance from free food samples in stores. Generally, they are harmless to bystanders as their primary focus is the free food. But occasionally, when herded together, they can emit noxious gas and block aisle ways - causing disruption to folks who are actually there to shop.
A sense of horror rushed over me when I realized I was shopping in Costco at lunch time. Droves of sample zombies converged to feast on the free offerings, clogging the aisles as they devoured samples as fast as they came out of the toaster ovens. I raced for the safe zone where samples of salad were being dispensed. Much like vampires fear garlic, sample zombies avoid anything with fiber.
