Funny you mention that, I do have at true story. 3 co workers and I go to a KFC buffet (yes they exist). We are behind a family of what appears to be African American's. They take the last pieces of chicken from the buffet, so we sit down and wait. When the new tray arrives, they get up, we get up and are yet again behind them. They take every single piece of chicken off of the tray...nothing else mind you, one guy looks back at us knowing we are waiting on it and proceeds to take them all.
So we sit down again and the cashier sees this and takes the next tray directly to our table so we can get some, we had already been there for 30 minutes without any chicken.
Similar happened to me at a Ponderosa buffet and another time at a grocery store where a black guy took all 5 fried chicken platters from the deli as I stood in line. Take it however you want but I would guess that perhaps stories like this might be why some equate black people to loving fried chicken. I like it too but damn at least I'm considerate about it and actually eat something with it without being all greedy
