Sir, it could happen but trust you me, on the african continent (generalization) the rest of the people in the public transport will definitely throw her off the bus just for disrespecting grown folk... And no Sir/Mum, i am not in denial, I have been to Kenya, Uganda, Tanzania and Senegal and I have seen how younger people have mad respect and fear for MAMA!
It would not happen if she was with her Jamaican peers. They would not tolerate that in the community. In this scenario, she is not among her people and decided to impress upon everyone, her understanding of the underbelly of the beast.
