It’s totally worth it.
Case in point:
Miss Print speaking to patron: “I’m not really sure. But if you just talk to that gentleman over there he can help you out.”
Gentleman in question: “Wow. That was so professional. That puts so-and-so [who randomly introduced GiQ as a librarian earlier] to shame.”
So worth it. Especially since I just always say that when referring people to the librarian.
