Throughout the concert I heard similar shouts from time to time. It's like in a classroom when a teacher is lecturing, some TA suddenly shouts 'HEY YOU! STOP DOING THAT!!!' to someone in an otherwise quiet classroom, which disrupts everyone's concentration. I don't know what happened but felt that was totally inappropriate. (For the record I was not wearing some ghetto clothes.) During the show, when Taylor was performing at the mini-stage, I heard a (male) shout near the stage, loud enough to disrupt Taylor's performance, and when I turned my head back I saw a yellow-uniformed guard angrily talking to someone in the crowd. Fortunately the gatekeeper was very friendly and joked around and made me feel welcomed again. Was he targeting me because I'm not a teenage girl or not accompanied by a teenage girl? I felt insulted. Even after I went through the gate and had my ticket scanned, he followed me and 'checked' my ticket again.
He checked my ticket again and again, asked me whether I was traveling alone, and went as far as asking me whether I was 'a big fan of Taylor Swift', in front of all of those people. Before I went through the gate a security guard started to harass me.
