I am very familiar with the case.  Please, link me to an article that spells out where this gay couple asked for the baker himself to be involved in the wedding, or that they wanted some image on the cake itself that was somehow offensive or went against the beliefs of the baker.

You clearly have it in your mind that this couple requested something special or different than what would be considered "normal" in regards to this cake - and I have found nothing to suggest that in any story I have ever read about this case.
