I never understood why some artists arrive late to their concerts. Unless something drastic happened that delayed you, there's really no excuse to do your job and get on stage on time. As an artist you are literally NOTHING without the support of your fans. They do not deserve such blatant disrespect. They're the reason you have success in the first place. Bon Jovi had every right to tell Bieber off. Bieber is an adult now and has to deal with the consequences and criticism of being a conceited celebrity. Bieber legitimately needs to start working on building his image up again because most of the public is done with him.
Well their parents would pay for them in that case.
It's a fair statement, may be a bit harsh at first but it comes from an artist that's almost continuously on tour. And considering the age, I mean he's 18+ so I guess a critical tea here and there right now won't hurt.
