I used to work at a restaurant, late night Janitor shifts. I would start 2am and get off around 6am. One night I had finished up early, so like usual, I poured a draft beer (the job had it's perks) and went to take a nap in one of the booths. The booth had a window, so you could see the empty parking lot of the neighbouring business. I finished my beer and dozed off. Shortly thereafter, I jumped up, startled from a loud screeching noise. I look outside, and see a shiny black van screech to a halt. The back doors open, 4 guys step out... I shit you not, wearing black suits and ties, like a scene from men in black. The driver stepped out and seemed to stand guard by the back doors of the van. Two of the suits walked around the front of the restaurant, the others went around back. I felt they were surrounding me, I was literally freaking out, I had no idea what to make of it, I remember feeling really confused. I grabbed a giant kitchen knife, and hid in a different booth with a better view, trying to catch a glimpse of what they were doing. I could only see two of them, they just seemed to be looking around intently, like they were searching for something. Then, I shit you not, the guy back at the van started making weird birds calls or some shit... the four suits came running, jumped in the back of the van, and sped off. It was so fucking weird. I"ll never know who these men were, or what they were doing.
