Racism is always there whereever you go, with that being said it still peeves me when it happens. Jambai you will need to prepare proper evidence because if you want t file a lawsuit you will need to cite when, where, who, how it happened and etc. Just stating one side of the story about the bad attitude and poor treatment may only be considered circumstantial unless it happened daily or regularly. You will have to go into details. But personally nobody deserves this.
