Yeah, nah. I find this incredibly hard to believe. It's extremely unlikely that even one behaved like that. Australian taxi drivers are immensely racially diverse, as it's one of the easiest jobs to get when first arriving here, and all would sell their child for a $20 fare. And you're telling me an entire rank of 20 drivers are somehow all racist toward indigenous Australians, like at levels they'd refuse a job? Yeah, nah.
Something seems off, like it was more her behaviour or condition. Or, ya know, the album she just released...
