When you throw s**t up here, that's an epic fail," Rihanna told fans."I wanna get your gifts but I don't want you to knock my people out. I swear to God, cut that s**t out."Really, chips? Chips though? That's that important?"Rihanna hit a fan with her microphone in Birmingham last month after they grabbed her during the show.
