We've recently hired a new server at the restaurant, and she's taken a huge liking to him (as everyone does; it happened to me). He's told me that she's been very flirtatious towards him, especially when I'm not working the same shifts they are. I've heard her refer to him as her "Restaurant Boyfriend". And this morning, he handed me his cell phone to look at a text she had sent him, so I started scrolling through the rest of them and she is very much not subtle in how she's feeling and is very much coming onto him. He didn't really reciprocate her advances, but was just instead being polite and evading her constantly asking to hang out. Nothing he's doing makes it seem as if he is interested, so I'm not worried about him. But I am really, REALLY upset about how she's acting towards him. But as he isn't my boyfriend, I'm unsure if I'm welcome in feeling like this and especially unsure if I'm in any position to say anything about it to him OR her. Am I crazy?
