Only if it's directly receiving government funds or dealing on behalf of the government should there be any restriction on whom they serve. Most businesses don't directly receive government funds. For example, it should be illegal for a charter school to refuse to accept a gay student because they receive funding directly from the government. Same with a vehicle emissions test business that provides registrations. Or a hospital that has an emergency room. Every business gets some amount of benefit from government services, but that isn't the same as it being funded by or operating in behalf of government.
