Atheists Denied Discount at Cici's Pizza Chain!

Atheists are discriminated against because of a sign that was posted inside several Cici's National Pizza Chain stores: ''Bring your church bulletin and get a FREE drink on Sunday!, with the purchase of an adult buffet.''  This sign is illegal, and discriminatory, and atheist families like mine are not allowed to get a ''free drink,'' on Sundays because we do not attend any church.  I believe Cici's Pizza understands this discount is unfair, and against the law, as they do not promote this discount on their corporate website.  The only way to fight this locally is by contacting the Civil Rights Commission, and to file a complaint, but that takes time and doesn't resolve discriminatory corporate policy.  After all, if only ''one kind of family'' can get a discount, (church attendees), what's to stop any corporation from this same kind of discrimination?  It's time that ALL families, even atheists, get the same equal treatment and the same discount.
