My non-hispanic-white college roommate and I went grocery shopping once (about 15 yrs ago), and since we would try to each buy half of general supplies but get our own hair spray, cosmetics, etc., we would check out in seperate carts. Repeatedly, my license number and drivers license were run through the "hot check system" keypad thingy upon writing a check, and hers was not. There are still knuckle dragging idiots (even on FR occasionally), but what are you gonna do?
Just goes to show that there is no shortage of idiots.
