Your link went to page 4-5 of the discussion, but did you read the first couple of replies?
Here's one of the first ones. "Maybe by, "We don't serve your kind here." They were referring to "dumb redneck coonasses." The only thing I got from this video is that some poor white trash doesn't like this gas station, so he stood outside, shouted some racial slurs, and video taped it. For some reason, he now thinks he will be a celebrity. God bless America! :p"
Now the video isn't even there for us to see for ourselves.
