Complaint Review: Sam's Club

I went in there to return an item I bought online that broke in transit. The baboon that waited on me said I was rude and foul because I wouldn’t say thank-you to her. I couldn’t believe the attitude. If the situation was reversed and I told her she was rude and foul I’d probably get arrested and banned from the store. Why are White people conditioned to take abuse from non-whites, especially blacks? Why is that?
