So I work in a grocery store, and have been for the past six months. I got to know every one in my store very well, coworkers and customers, and I've made some really great friends while working there. I'm a pretty quiet but likable person at work, and I've never had any fights with anyone I work with. All my coworkers seemed really nice and accepting until last night. It was about 9:30pm and I was sweeping the store with an older coworker (I'll just call him Joe here) and we pass a couple, one of the two is a young woman with bright pink hair and the other appeared to be male (I'm not sure about his gender, but will use male pronouns for the sake of ease) and was wearing short shorts and a black leather purse. Upon seeing the couple I smiled, just 'cuz I'm a romantic and seeing happy couples usually makes me happy as well. My second thought was how I really liked his purse. Joe and I greet them and continue sweeping, they say hey and go on their own way. They barely get 15 feet away when another one of my coworkers approaches Joe and I (I'll call this guy Chris), and says quietly, "did you see that guy?" I nod and Joe says yeah, neither of us must have seemed very interested in judging him because Chris gets angry. He begins to talk about how men shouldn't dress like that, and how thee girl with pink hair should be with a real man. I stay quiet, trying to think of what I can say to defend this guy without ruining my friendship with Chris or accidentally outing myself (I'm a translady but I've gotta live in guy mode a bit longer), and Joe just shrugs and is obviously just trying to ignore Chris. Chris seems totally unaware of how uncomfortable he's making the two of us and he continues talking, and eventually says, "I just want a baseball bat... A bat and a room with no cameras with that guy. Is it bad I think this way?" and at this point Joe looks really uncomfortable and says, "Just a little..." At this point, I feel terrified of this guy, and really pissed so I sarcastically repeat Joe's reply and tell Chris to let people do what they want, as it isn't his place to judge. He tells me "you can do whatever you want to in youre own house, but not in front of me," and he begins laughing and walks away. At this point I'm pretty angry and freaked out, but Joe and I keep sweeping and try to forget what Chris was saying. Later that night I manage to find my supervisor and I tell her what Chris said and that it was really creepy and really offended me (I was also shaking the entire time) and she reassures me that she'll tell the store manager and get him to speak with Chris about the incident. However when I left the store, I actually got off at the same time as Chris and I nervously started making small talk with him, and he talks back to me and is acting pretty normal but his tone of voice sounds really menacing and I get scared that he overheard me telling the supervisor what he said. But I got home safely that night, and fortunately have a few days off of work this week where I won't have to see him. However I'm actually pretty scared of this guy, as he was once my friend and invited me to play paintball with him and his wife once, and I really hope he doesn't know or learn that I'm the one who told on him as I feel he'd get really mad at me, maybe try to hurt me if he got in trouble or lost his job because of that. And even though his threat wasn't directed at me, and the guy it was directed at wasn't there, it still felt like he was threatening me. I plan on keeping my job throughout my transition as I get very good benefits, pay, and I'm on good terms with all my managers and supervisors so I have a chance to move up really fast, but his threat was basically like him saying, "if you transition while working here, I will eventually beat you up." So now I'm pretty scared. Is there anything I should do? Should I talk with the managers, or Chris, or what?
