Coincidentally, if you would've asked that before Friday, I would not have thought of a single instance. However, Friday I was surprisingly the victim of blatant racism. It wasn't because of the person I am or any level of personal aura, it was very clearly because of the color of my skin.
I stopped into a chicken place to grab some strips quick for lunch. The black dude behind the counter completely stonewalled my existence. I was the only one at the counter or customer within 50 feet of him. I stood there waiting for service for about a full minute and he just looked right past me without the slightest acknowledgement but it was very clear he knew I was there. Finally, I interjected "I'd like three strips please". He grumbled something then said "sauce?". "No thanks", I said; then he just proceeded to stand there and not serve me.
Right after that, a light-skinned black gal walked within about 20 feet of the counter and the black dude behind the counter smiled and exclaimed "can I help you, miss?!?" "No thanks, I'm just looking at the menu" she retorted.
Finally, the south-central-Asian (Indian/Pakistani/etc.) gal coworker of the black dude stepped in and rang me up and got me on my way.
