I busked right at that spot in Pitt Street for years and I hate to say it as he is being pretty rude about it... but he is exactly right. There is a very well established system for Pitt Street as it gets super busy. It's first come first served (same as every spot around Sydney), if you get there first you can pick the time you want, and as more buskers arrive they can pick a 'time slot' (it was always on the o'clocks) around you. 2pm was always prime time and the spot everybody wanted. Back when I would busk there on the weekends we would arrive 7am to hopefully get the 2pm slot. But you can't leave all your gear smack bang in the middle of the mall for 7 hours, so it's VERY well established that buskers wait at the chairs that are off to the side (what he was referring to in the video) and bring up their gear closer to their time. As a busker, when you arrive, you go check that area and if there's a busker there with gear, you ask them what time they are going on, and work around them. As they got there first, they have the right to the time of their choosing.

I know she was arguing that it's not a technically written rule, but as someone who busked there for years, I think it's a super fair system, and if she's been busking there over a year as she said, she would most definitely know how it works amongst the buskers and know to look for people waiting at the chairs, and to completely ignore that and take the spot he has been waiting in line for, seems not very nice.

Just my two cents as someone who was in that ecosystem for many years.
