I would most likely agree with the decision as well, if it was based on a legitimate pt condition that warranted not taking both pts. It sounds like this was more about not wanting to transport two pts rather than being uncomfortable with it. I don't know anyone that wants to take multiple pts, but we have all done it. It's just part of the job.
I find taking two stable PT's to be quite fun sometimes, lol. Kneeling on the floor taking vitals, getting them both engaged in conversation about each other, their conditions, etc.
