It was my second week working at my town's local theater and my boss (who's been running the place for years!) forgot to mention Otis. Otis was the first owner of the building. He used to hold illegal drinking/gambling parties in the basement a long long time ago. There's a local legend that he was shot when caught cheating, but I don't know if that's true.
So I was the only one working that night besides my boss, but he was outside washing windows. I just finished refilling the candy counter and I turned out the light. I went upstairs to get a some popcorn bags and I thought I heard Ted (my boss) climbing the stairs with his cane. But nobody was there. Honestly, those stairs are loud and someone was definitely on them.
I got a little freaked out. I started to walk back down, but the door slammed shut and locked. I screamed and pounded on the door until twenty minutes later, Ted came upstairs and helped me. He just chuckled and told me Otis was a practical joker. "Next time he does that, Ted told me, "just scold him and tell him to open the door..."
I encountered Otis again another time, and he locked me in the supply closet. My heart pounded but I stayed calm. I said in my sternest voice possible that I was busy and he needed to unlock the door. He did. Now I have a friendly relationship with Otis. He'll hide the candy or flick the lights on and off or only once did he pull my hair. I got angry and told him never to touch me because it scared me. He hasn't done anything of the sort since.
I just wanted everyone to know that not all ghosts are bad. Otis definitely isn't.
