Here's the NAACP press release:

Sure, there's undoubtedly some politics going on here...and a few less than credible plantiffs jumping on the bandwagon (Crackerbarrel pointed out a few in their statement)

Still, it seems pretty clear that some African-Americans have had a less than warm welcome when they've gone to Cracker Barrel to have dinner. One has to wonder why there's 400 people claiming to have witnessed racial discrimination at this restaurant. I've gone out in the presence of African-Americans far too many times in my life, and noticed mostly subtle but once in a (rare) while not so subtle differences in the way people greet and treat us, to believe that there's absolutely nothing at all to these Cracker Barrel allegations.

I don't believe that the Cracker Barrel management is racist or actively practices racism. But I could certainly believe that the management has been negligant in their responsibilites to monitor and correct the inappropriate actions of (hopefully) a small number of their employees.
