Wow, didn't expect this many comments. I talked to my boss about it today. The coworker had actually lodged a complaint, but conveniently forgot to mention the whole thing about a lighter that looks like a gun. He doesn't work there anymore. The main reason I thought I was going to lose my job was that he had worked there for a lot longer than I had. I've been there less than a year. I was worried that he could have said anything he wanted and I'd end up with the shit end of the stick just because I was new. As for whether or not I over reacted, maybe I could have taken a moment to analyze the situation, but it's not like he was trying to take my wallet or telling me to do anything. He silently pointed a "gun" at me. The last time I spoke to him I had said to him was that his English sucked and he shouldn't be teaching (I work at an ESL institute). The next time I saw him, gun in the face. I asked a cop friend from the states about it, he said if someone pointed that at him they'd get shot.
