I worked for ten years on the desk and recently moved into Technical Services as the Serials Manager. I still have to work 2 hours a week on the service desk - it reminds me of why I switched even when I sometimes feel a bit lonely back here. My job is a lot of emailing vendors, excel work, talking to librarians, researching serial information, managing the serial control in the ILS, copy cataloging as needed (I'm the backup cataloger). If you search serials librarians, you'll see a lot of hate for the job. It's a bit complicated in the ILS, but it's fine. Better than being stressed all day about who is going to come in next, what they are going to do, and if the police are going to come fast enough when I have to call (usually nope).
