I think I saw racial prejudice today
I was shopping at Kroger. A black guy who has worked there for well over a year was manning the express register (15 items or less). There were 3 other lanes open, for big orders, like mine. In each lane, there were older white people with 3 or 4 things each. I can't help thinking that they would rather wait behind big orders, than get checked out by a black man. I'm friendly with many of the Kroger clerks, including this man. He is friendly and helpful. He told me I should come through his lane, when I was already unloading. I didn't take him up on it, because the last time the clerk let me go through the express lane with a big order, an old lady yelled at me that I had too many things. He wasn't busy right then, so he came out from his register and helped me unload my cart, then helped bag, then went back to his register when someone came through. The older lady clerk checking out my order, the younger bagger, the black clerk and I all had a quick conversation about the missing plane, so the isolated old people missed out on that-- and some decent human contact.

But, I've seen seniors just take the first checkout lane they see even if they only have a few items. I blame the lack of visibility at checkouts, these days. You have to walk all the way up and down the aisle in front of the lanes to see what's going on in each because they have so much crap stacked up around the registers you can't see heads.
Another possibility is the senior outing. I live in a retirement town and they like to stick together in little gangs at the grocery store. One may have picked that lane and the rest followed...like ducklings. 
Let's hope that's all it was.
