Was this postmaster out of line to do this to a biker?

I went to the small town where my daughter lives but first to the post office. This unkempt man with shoulder length blonde hair pulled up on a motorcycle and gave the postmaster some money. Afterwards we had to stand there endlessly while the postmaster held the money up to the light. In fact, it was such a sad and annoying scene I walked out. Was this unforgivable behavior or warranted? The entire town revolves around church attendance.
