Restaurant's "Praying In Public" Discount Raises Questions

Inquisitr and HLN reported yesterday on a Winston-Salem, North Carolina restaurant that offers a 15% "Praying in Public" discount.  Apparently Mary's Gourmet Diner awards the discount to diners when a member of the wait staff sees them pray over their food. The story has gone viral, and some raise the question of whether the practice violates the religious discrimination provisions of the 1964 Civil Rights Act.
