I don't have creepy pasta, but I do have a story for you. Not gonna green text (newfag, whatever) but I hope you like it.
During the summer I work at a local grocery store, decent sized. On this particular night, I pulled the closing shift. Sucks, because for the last hour or so people raely come in. So we end up cleaning and such. Anyways, I had to dump all the garbage bags in to the dumpster out back. It's a short walk across a gravel parking lot, and it was dead quiet, all I could hear were my footsteps crunching and the bags flopping around. I remeber it being cold for a summer night. I put the bags in the dumpster, got back in the store and closed and locked the door, as is the rule. I take maybe 2 steps away when there is a BOOM as something hits the door. I mean, there was enough force that the padlock started bouncing around. Feeling ballsy, I went to the door and listened. Silence. Then the door started shaking, like someone was trying to open it from the other side. It stopped, and i listened again. Still silence. No footsteps on the gravel or anything. Fed up with this bullshit, I unlocked and opened the door
There was no one there. Needless to say, I was a little spooked, and always looked over my shoulder from time to time whenever I worked the closing shift again.
