I don't normally get upset if people forget my name. But I did get upset once when I met a guy and he forgot me. I was hanging out with a mutual friend and was quickly introduced to this guy at a bar, then the same mutual friend and I were at the same bar when the next time I saw that guy he forgot he met me already but I shook his hand and reintroduced myself, this happened another time at the same bar which annoyed me but I went through the process, then the next time this happened at the same bar I told him we already met several times and refused to shake his hand because I already had shaken it before. He awkwardly laughed it off as I just stared him down, then he eventually left my friend and I to hang out alone.

Our mutual friend thought that was excessive on my part, but that guy sure as fuck remembered me after that.

If he had forgotten my name, that's understandable. Totally forgetting me several times, fuck off.
