i experienced this myself once when i was going to see a movie, i was standing there in line with my ex and suddenly this guy tries to move in front of me and my ex while doing this he pushed my ex away. She said "hey!" and nothing more. then that guy turns around at my ex and says bitch to her. 2 big steps and I was in front of him! I grabbed his troath and took him by his throat to my ex and screamed in his ear: say sorry! I saw his eyes turning away because of the lack of oxygen but he still managed to say a quiet "sorry". so i released him and then kept on waiting.
what would you guys do?
