What I witnessed at the Shoping Mall

So I went to shop yesterday at a mall and i came across a white guy who also came to shop, he asked for some products and was directed to where they are, he went there and I noticed that he would read some things on them before picking some he would pick some and reject others.
After he was done I was forced to go and enquire why he didn't buy even toothpaste that he asked for and I was told that no matter how good any product is, once he sees made in Nigeria on it, he doesn't buy. That he's their regular costumer.
I was really angry cos I started wondering what he takes us for.
