From the TMZ article and the video I've concluded that Azealia isn't in the wrong for anything at all except for saying "******" which I personally don't care about, but others do.
The article says the Attendant grabbed her bag from her and she lost her balance and fell into the seat (which would DAMN well piss me the **** off too because don't touch my ****).
Also, she's pulling backwards which to me is signifying the exit is behind her, which no one is blocking, so why the **** aren't they letting her grab her **** and leave. She's only in the way of everyone else and if she was able to grab her stuff, she could leave.
So like why weren't they letting her grab her ****?
