"Case on refusal of gay customers denied" (whew to that)

The USSC refused cert. in the Elane Photography (a corporation) case, rejecting a claim that a public accommodations photography studio could refuse to serve a same sex ceremony. Glad they avoided this can of worms. Just what is "expressive" enough to refuse service? Prof. Volokh was in the forefront in getting the case heard though I felt he repeatedly didn't address the breadth of the claim. The religious rights claim was no longer active.
