Walked out

I’m not going to go in depth but I had to walk out because my GM wanted to side with the Manager about how he was “Joking” when he would hit on me and ask me to dinner and try to get me to neglect my job to spend time with him. He’s 50 I’m 21, ten years ago he would have been 40 and I 11. Even if it was a joke how is that acceptable?
