I think the young woman who just had the baby and talks about how baby's reaction to winning the lottery, is one of the more authentic ones. She doesn't seem like she's forcing anything there or trying to act. It seems like her time is also shorter than some of the other people's spots, so this might also help.
I have singled out the long haired guy as liking more than most of the other's, up until when he says ''Anything to show passionate of a Devils fan I am'' or whatever it is that he says at the end. It seems like he's trying to lay it on thick, but I don't hold it against him. He isn't an actor.
The one with the young woman whose day is very structured (?) and her jersey HAS to be in the car or else. Get a grip.
