Usually they're more subtle

A Nigerian man was rejected for a job in Belgium because the Belgian businessman's dog is racist:

The 53-year-old man Nigerian told De Standaard newspaper he arrived at the Belgian's wrought-iron business and was immediately confronted by the barking dog.

The Belgian turned the man away before he could even enter, and wrote on his labour office letter that he could not hire the man because of his colour, adding there was a risk the dog would bite him.

The local labour office has concluded that the Belgian was racist and has removed him from its list of potential employers.

"My dog is racist. Not me," the Belgian told De Standaard.

As the Nigerian man said, usually people try to be a bit more subtle when they're discriminating against him.
