"No poor people allowed!"
"Hayama Exclusive Luxury"
Gramping apparently refers to "camping with the grandparents".
Problem is the next line.
That particular location/event is "exclusively" for indulging in / being able to afford (lots of) luxury.
Or in other words: commoners = ordinary people are NOT welcome.
* maybe everybody with an annual income below 150,000 USD will be shot on the spot???
I do not like those snobs (who are, incidentally, disrupting/destroying the local society).
I very much prefer talking to the old fishermen (Hayama used to be a completly unknown fishing village).
