The documented job responsibilities of an in-flight supervisor give is a pretty good idea ...

- Deliver best in class customer service
- Deliver a high-quality onboard experience to drive improvement in our Net Promoter Score (NPS)
- Ensure daily company goals, policy, and procedure compliance are met

I'm confident playing on your personal device for the entire duration of a flight do not support any of these three.
