Hold on there, buckaroo! Context certainly matters. In other words, different behavior is “normal” in different types of public spaces.
If you’re in a public park, throwing sticks for a dog to fetch is perfectly acceptable. The same is not true in the grocery store. And the unknown-to-you world-at-large has no need (or right) to watch and comment on your stick-throwing techniques or your produce-selection prowess.
To what extent does a commercial flight qualify as public space, anyway? They are a private carrier. They certainly have the right to tell you to turn off your danged phone.
