Which of the PC's were you in?
We were in the one by C102 and it was slow. Barmistress served without difficulty and girls stocked the snack bar, while other girls picked up the trash, that the passengers left behind and did not toss into the bins provided. I hope you don't leave trash behind for someone else to pick up!
I have been in all of the EWR PC's on many occasions, and have never experienced or seen what you have. We stopped into the LAX PC and it was empty about a month ago. The bartender took care of us, and the front desk anwered my questions regarding the still in the Club.
It is best to look for the good things in life, rather then the other!
