You are right in a way & wrong too .It's like having a favourite restaurant, a neach you like or some hill station you enjoy. If too many people start crowding it, you can't enjoy anymore even though everyone has the right to go. So you hope that not many people go when you are going. Like I avoid going to a mall on the weekends and holidays and will never go anywhere touristy on Christmas, Diwali etc. So similarly, I want the lounges to have a reasonable level of people.
I too feel now 3rd AC railways has become sleeper class & sleeper class is General class
When i used to travel back in 2013-2016 in Ac .
No one dared to Even look into Ac without ticket they would simply avoid area near AC coaches.
But Now mostly people can afford Ac class hence rush
Same with Airport.
Earlier very less people knew about lounge access.now everyone has debit card/Cc .and they know through YouTube, family etc
So more people are there to avail free service.
Rather than Askin for better facilities from airport / company we are into Criticism of common one for whom anything free is happiness.
