Hotel Refused to Let My Boyfriend and I Share 1 Bed (Same-Sex Couple) What can I do?

Upon checking into an airport hotel next to O'Hare in Chicago, the hotel receptionist refused entry until I upgraded to TWO beds instead of ONE. He even stated "if it was a man and woman, one bed would be fine, but I cannot allow to men to sleep in the same bed". I had to pay $20 extra for two beds after he refused a total refund of the one night rate I had already paid.

I am angry, humiliated, and traumatized. I know this is light discrimination but man does it feel terrible. I understand so much more about the injustices in my country and the world now just with this tiny civil violation. My entire sense of safety is totally in question after this tiny incident.

After researching, I see that this hotel has broken the law. What can I do? What should I do? Am I legally entitled to anything to make this right? This is a small hotel chain with several hotels across the Midwest.
