You want to be treated specially and shown that I want nothing in life except the job you are offering. I want to be certain my children have food on the table when my savings run out next week. Do you see the difference?
I understand your point that someone acting like they need to bounce from the call can be irritating to deal with, but it is a reality that several candidates might have a whole lot of interviews lined up as closely as possible to maximize their chances of actually landing a job. Add to that the increased commitments of a household, and I don't think it is unrealistic to expect a little empathy from the person on the other side of the call.
It is fair advice to say the candidate should try to remain calm and "not create the perception that you have something better to do" as you initially suggested. It is not fair advice to ask them to free up their entire day and not have any commitments other than a single interview.
