edit:
However, the Freedom from Religion Foundation, an atheist group, was not impressed with this discount. The foundation’s staff attorney sent the diner a letter pointing out that offering a discount to customers who visibly or audibly “pray” at some point during their meal is a violation of the federal Civil Rights Act.
A restaurant, after all, is a place of “public accommodation.” The federal Civil Rights Act of 1964 requires restaurants to be available for “full and equal enjoyment” of all customers.
All persons shall be entitled to the full and equal enjoyment of the goods, services, facilities, privileges, advantages, and accommodations of any place of public accommodation, as defined in this section, without discrimination or segregation on the ground of race, color, religion, or national origin.
Everyone who walks in the door should be treated equally. You can offer a student or senior citizen discount, because age and educational status are not protected groups under the Civil Rights Act.
