So obviously the question IS about race and commercials, not who actually delivers for you.I'm glad someone got my intent. In my opinion Amazon are the ones who seemed to make this commercial all about race in the ending scene. Probably because it's black history month-which is cool as long as what you're presenting is true and in my experience it's not having never seen a female express delivery driver period let alone a black female one.
Amazon chose not to use a brown or even black male actor as the driver- which is my experience too who mostly delivers my packages.
Come to think of it if it was a black male driver in the commercial it wouldn't have even struck me as odd at all and I would never have made it a thread topic here.
I find Canada post quite varied, FedEx and UPS to be majority non-white while as leafscom mentioned, Amazon (and other subcontractors) are generally poorer and more desperate for work. Where I am, the vast majority are non-white (though far more men than women). Fact is in a city like Toronto, the people willing to take crappy jobs like Amazon delivery are poorer and statistically that means more likely to be non-white.
And in case the OP missed it, there are many jurisdictions in the US where there are a lot of black people and they have all kinds of jobs. Get over it.
