People always get my name wrong?

If someone is getting your name wrong, then definitely correct the person. You don't want people to get your name wrong because your name is a big part of your identity. If someone mispronounces your name, just say, Oh, I'm sorry to interrupt you, but you happened to mispronounce my name and I just wanted to let you know the right way to pronounce it". If you say it like that, then the person is not going to be offended. If you laugh and get obnoxious, then yeah, the person will feel like a fool.
