It still amazes me that racism is alive and well in 2017.
Just because he stays calm and cool doesn't mean he wasn't being awful. This is from the caption on the original Facebook post:
This happened to a friend who works at a Walmart in the Dallas/Fort Worth area. She feels very scared since this incident. And I am wondering if Walmart will do anything to protect its employees of which a large number are minorities.
A WalMart employee, Adela, had to find someone else to help this man because he refused assistance from anyone who wasn't white.
This incident kicked off after this man complained that he couldn’t see well with the glasses he was picking up, so after Adela referred him to a doctor, this idiot demanded to be helped by a white employee, and then that kicked off his rant. (Mandatory)
When we hear him start speaking at the beginning and asking about paying a woman's hospital bills, he's apparently talking about a black woman who was in an electric wheelchair. So, a customer, most likely.
Adela showed the video to her supervisor after the incident, who said they were "shocked", which I'd say is a normal reaction.
Of course he's already been doxxed, which is when people search for and publish private or identifying information about (a particular individual) on the Internet, typically with malicious intent.
Adela, by the way, has been a tax paying US citizen for 20 years.
