I would've guess that guests at GF would seem to be more entitled since they do travel a lot more than just silver (or oneworld sapphire) members.

I would be the complete opposite since it would be my first time ever in a lounge and would like to finally enjoy the fruits of my mileage runs (probably second time since I will try to enjoy the lounges at JFK).

I will be travelling on a Tuesday (leaving JFK Monday night) in late Feb so I hope it won't be too crowded. Probably just a lot of business people.
