On occasion, we have been greeted this way by a thoughtful desk clerk. More often, the clerk gets slightly flustered and says something like: "There seems to be a mistake with your reservation; I'll give you two beds." We quickly and quietly tell the clerk that a king bed is just fine. Never had any problems. But having said that, we found it is generally easier if only one of us registers while the other sits nearby in the lobby. There really is little point to having two bodies hovering at the desk, straight or gay.
