In the words of Reginald...ahem...Denny, "Can't we all just get along?"
Cracker Barrel has an anti-discrimination policy:
CRACKER BARREL’S PUBLIC ACCOMMODATION POLICY STATEMENT
It is Cracker Barrel’s policy, fully consistent with federal, state and local law, that no Cracker Barrel employee may discriminate against any Cracker Barrel guest or would-be guest on the basis of race, color, age, national origin, gender, religion, disability, or sexual orientation.
For instance, Cracker Barrel policy prohibits: (1) providing preferential seating based on race or color; (2) seating guests out of order based on race or color; (3) seating guests of a certain race or color in a certain part of the restaurant on the basis of their race or color; (4) refusing to serve guests based on race or color, including trading tables with other servers to avoid serving guests based on race or color; (5) providing slower or less courteous service to guests based on race or color; (6) making any racially offensive comments, including assertions that certain races or groups tip worse than others. This list is for example only and is not exhaustive.
Cracker Barrel’s policy of "Pleasing People" does not include accommodating customer or employee prejudices based on race, or color.
Any Cracker Barrel employee who observes what he or she thinks may be a violation of this policy must report it to a store manager, district manager, regional manager, or to Cracker Barrel’s Home Office (1-800-333-9566). Any employee found to have violated this policy (including failing to report a violation that he or she observed) will be subjected to severe discipline up to and including immediate termination. In addition, any Cracker Barrel employee may report a violation of this policy to the applicable local, state or federal enforcement agencies, including the Civil Rights Division of the United States Department of Justice (1-800-896-7743 or 1-202-514-4713).
Cracker Barrel and its employees cannot and will not reprimand, penalize, or otherwise retaliate in any way against any employee who, in good faith, opposes or reports alleged discrimination, either to Cracker Barrel or to the applicable local, state or federal enforcement agencies. Any employee found to have retaliated against another employee who opposed or reported discrimination will be subjected to severe discipline up to and including immediate termination.
Furthermore, a free meal was offered to make up for the delay in service. I don't see how Sharpton and Co. could win.
