I know someone that worked there, who said if they have someone that they really don't like the look of they'll completely ignore them, not even bother with a reply. This might have just been that one store, however.
I suspect they had a pretty high volume of applicants. If he's that bothered I suggest he rings them/goes in and asks them what happened. Realistically, he didn't get the job if they never called him back, but they might be able to give him some feedback as to why not for future reference.
