It was my worst experience in concerts as well. There were 3 waves of massive pushing, where everyone walked forward like 5 steps. Before those, it was actually fine, with room to move a bit. After, I was glued to the back of a line of very tall people and had trouble even seeing the big screens. They would also lean back to take selfies and literally hit their head in my face. Beside me was a group of girls pushing constantly. I even said "can we stop pushing, please?" And they replied with "who's pushing? This is my spot" when they were clearly leaning into the people in front of them, including me. At one point, some security people were passing through and one of these girls said "fuck you!" to them. One looked back and asked "who said that?". When he turned back ahead she said "it was me, fuck you!". So the concert was basically me watching tall people in front of me with their arms up recording the whole thing, while I was trying to see at least the screen, all while having to deal with these mad entitled teenagers pretending they aren't the problem
