It would be good if racial resentment didnt waste so much of everybody's time. I'm absolutely certain that not only did he waste your time, but he wasted his own time, and the time of everybody who was in line behind you just because he felt the need to flex on random black people.

I often say to my friends who encounter this that being a racist must be like having a head full of bees, only less pleasant. They just be bothered by the simple existence of other human beings on this planet!
