Idk what it is, but I find it quite perplexing that none of you are aware that it is standard obligation for main artists to present themselves on stage between one and two hours after the time on your ticket. This is for pretty much all concerts. Djs and opening acts are not there for nothing. No opening act or DJ = a much sooner appearance by the main act.

Y'all must not get out much or go to concerts much. She was not two hours+ late. Next time, just analyze how things are setup at a concert.
