Padre Pio's idea. Had to be.

Another typical morning, working a cashiering shift. Smile, chat, wish I had coffee. Scan items. Offer store credit card, get refused, take money, say goodbye. Greet next customer, smile, chat. Wish I had coffee, scan items, offer store credit card...

"Oh, that other woman dropped something." I glance up - that's not part of the routine. Maybe she dropped chocolate espresso beans, that would be nice.

My customer picks the something and hands it to me - it's a soft vinyl pouch; the contents have a familiar feel. "A Rosary?" I hesitate, between the customer in front of me and the one already out the door. I take the lazy route out. "Well - I hope she comes back for it." I probably wouldn't recognize her anyway, not with my memory for faces. And anyways, rosaries get lost. It happens. I'll drop it off at lost-and-found on my break.

During a slow period later on, I take a closer look at the rosary case. It's double-sided: one side holds a chaplet of some kind, from Kibeho in Rwanda - a Marian apparition that warned of the coming genocide. It's not just any rosary. Also there's a 3rd-class relic of Padre Pio. As for the other side of the pouch...I choke, and check quickly for any name or phone number. There's none; just the three reliquaries with 1st-class relics of Elizabeth Seton, John Neumann, and Pius X. From then on, until I am able to go back to customer service, that pouch does not go out of my sight. No way.

The lady was elderly, so probably a local; there are three parishes in town and odds are she is a parishioner at one. A few calls later, all of them will (hopefully) be running notices in the bulletin. If she doesn't come back, there's a note with the relics saying not to throw them out.
What to do with them then, considering my laziness at the start, I'm not certain.

Update: She did come back for them.
