Amit Patel lost his sight five years ago and since then he's had to rely on his loyal guide dog Kika in order to get around. An angry commuter either didn't care or didn't understand the concept of a guide dog, so he harassed the pair on an escalator, trying to force them out of his way. Please know, dogs like Kika are doing an important job.
Moving onto a very different type of "animal on an escalator" story, a mall in Russia had the unwanted type of mallrat show up. A real rat had made its way onto the escalator, probably looking for the cheese shop and terrorized the customers. No word yet on if this rat was looking for a pizza.
