What's up with all the scammers outside Deloitte Towers??

Every single day there are people standing on the footpath and roads trying different kind of scams on people walking by. I've experienced so many, from random family standing outside a car begging to gpay money for food for their kid (they have a car but no spare change?), people asking for donations, people making fake stories like losing wallets etc. What's more disturbing is they keep on calling out to random bystanders and people walking home and it's scary especially late at night. I just pretend like I didn't hear anything with my headphones on. Every single day this happens. What gives? I've never seen these many scammers in a single place in my life consistently every single day
