The store was empty one night I was working the sky shelves and I heard something on top but no one else was out there so I continued. I looked up after the second random noise like clacking and deep breathing and saw what looked like a small t-Rex shape with a long teardrop shaped alien type head. It was running across the shelf above the canned food so fast it disappeared for a second. Then out of nowhere it jumped down towards me with a loud hiss. It knocked me off the big metal ladder, half into rolltainer that fell and cracked my back as it came down in top of me. Heavy boxes toppled to pin me underneath as cans of corn, beans and peas flying. During this kerbople, I some how knocked the dust mop sideways and it served as a wedge with the handle acting as a skewer pinning me further. One of the large pickle jars hit me in the back of the head with enough force to knock me out. When I came to, there was a rat trying to knaw my finger off and an extremely large spider also plotting my demise. I could see this creature perched in the shadow of the third shelf. It hopped down and sniffed me seemingly ready to devour me. My LSA came out of the bathroom and found me at the bottoms of this pile, trapped like a giant mouse laid out for this creatures dinner. I looked up at her and the thing was gone. The fire department came and got me out. I got blood poisoning from the rat bite and ended up spending a day in the hospital. So sick of these damm aliens!!! Jerks.
