Man alleges that he was denied entry into a Chinese supermarket in Abuja because he's a Nigerian

Chinese supermarket in Abuja where Nigerians not allowed access. 

You will be suprised to hear I went to a supermarket today and the security asked me what I needed from the gate and said that Nigerians were not allowed. 

We need to do something about this and I'm starting now. Any advice cause I'm taking this to the next level. They cannot operate here like that.
