I hate to say it, but in my experience Boomers and Gen X seem to have the worst manners right now... They feel entitled to respect and think it's ok to talk down to the generations they raised. I think it good to be nice to everyone and be polite, but the amount of times I have been told I'm wrong or that's not a good idea because I'm young is mind boggling. I'm not always right but more often than not in the context of the situations I have been being the subject matter expert. It's pretty wild what one has to deal with in the cooperate world.
