Are you serious????????

So I get on this plane friday. they spend the first 30 minutes telling us to buckle in for they take-off. The attendants are quite adiment about this. I am fine with this. I then think well this must happen on hundreds of flights a day. Also cool with me. However then they took it too far. They get on the speaker and show us how to use the seatbelt and "properly adjust" them. Come on..... Quit insulting my intellegence, and just toss me my bag of stale peanuts please.
