When you open your business to the public, you have to conduct 'fair and equal treatment' to each person who voluntarily walks through your door. You cannot deny access to your business just because a customer is one of these protected classes. You cannot refuse to sell to a customer just because the customer belongs to one of these classes.20-13-23. Public accommodations--Unfair or discriminatory practices. It shall be an unfair or discriminatory practice for any person engaged in the provision of public accommodations because of race, color, creed, religion, sex, ancestry, disability, or national origin, to fail or refuse to provide to any person access to the use of and benefit from the services and facilities of such public accommodations; or to accord adverse, unlawful, or unequal treatment to any person with respect to the availability of such services and facilities, the price or other consideration therefor, the scope and equality thereof, or the terms and conditions under which the same are made available, including terms and conditions relating to credit, payment, warranties, delivery, installation, and repair.

I want to add 'lawfully carrying a firearm' to these classes because I have a need to carry whereas the business does not have a need to deny.
I don't carry for preference, I've actually had to use my gun. No bushiness can demonstrate a streak of lawful CCW carriers committing crimes, that the business would need to ban otherwise lawfull carry.
