really annoying commerical with a message

[Voltron87]

There's this commerical I've been seeing on TV way too much, some white guy in a suit is getting lunch. His hispanic waiter gets him plain bread instead of whole wheat. The guy starts yelling at the waiter, "hey man, i asked for whole wheat, 'el wheato'". the other people at the restaraunt give him this disgusted look. Then the white dude (who is really overcast to look like a douchebag) says "well if you want to work here, you have to speak the language, you know what i mean?" and one of the patrons gives him this solemn goofy look and says "No sir. I don't." Then there's this voiceover about some anti racism organization or something. Its logo is a candle or something.

wtf is it even supposed to prove?
