I found a little velvet bag of very nice jewelry once at the Ritz Carlton. I turned it in at the front desk. Two days later I called to see if it had been claimed. They had no record of it being turned in. Their security department was very interested in who at the front desk I gave it to and exactly what time I turned it in.
Good on your part! Maybe it would be better next time to demand a receipt (with name /badge #) from the employee next time, if they refuse, don’t let them take the lost goods.
