He has a good point. I got some when I first got hired by a major because I was so damn proud of myself. But soon I realised I don't need them. Alaska give us a kind of by-fold card with, "From the Captain" on the front. I think I may have used one once. I think I gave it to a pax for helping out in a medical emergency. That was probably a good use. These days, however, I don't really care much to interact with the pax.
