A TV-presenter of a fairly popular TV-show with an audience in my country once told an anecdote that they wanted the admission for the audience to be free. But when the tickets were free, a lot less people showed up. When they changed the ticket to be the quite arbitrary amount of 7 EUR, suddenly the theater was full every time.
We naturally go for scarce things first. A few examples of this:
- I'm not particularly into castles, but I've visited a fair few while travelling. I lived in Norwich for 10 years, home to one of the finest Norman castles in the country. Did I visit? Did I heck.
- When your favourite film was on TV you'd watch it every time. Then when you got it on DVD you'd never watch it again.
- Give a dog some miscellaneous leftovers and notice how they prioritise ingestion.
Not sure it's really the same entitlement phenomenon the GP was talking about, though.
Context is king. A famous cello player playing on streets is valued less and is valued more when playing in a stadium. This is the typical framing phenomenon which psychology has discovered about humans. Even what colour we perceive changes based on surrounding context so not surprising.
