Club lounges can be worse than regular buffets no doubt.
I think there can be some entitlement there, especially the more high end the lounge.
I've seen very well off folks at very high end club lounges basically stand at the horderves and eat well talking on their phone as if it was their personally buffett. This is not just a one off.
We are at the point where if we cant get to the lounge at opening we dont go at all - unless its just for drinks or we know it is very well run.
I get the staff is afraid to say anything in some cases, but if you put out a big bowl of peanuts how about you put a spoon in it so maybe people wont just eat from the bowl.
FWIW - I do find the RPR lounge pretty well run, I cant say the same for the Disney ones - many issues there with staff and guests and I have been to 4 of them - Ill never spend the money again.
