Not trying to defend or something, but yes Rihanna is rude, but never with her fans, she always takes time to speak, sign autograph and take picture with them, she just didn't have the time do it, because Rihanna or Prince Harry or anybody else, the plane scheduled is fix, and they don't care if you're in or not.
Lol, sis, it takes .4 seconds to sign an autograph, so don't give me that "she didn't have time" BS.
