It's amazing how fast some are to call a simple observation a complaint.

I saw an even funnier one a while ago. It was like 5:40, don't remember which airport it was, but there were these two people lined up waiting for the lounge to open at 5:45 or 6:00. I laughed as I was walking by apparently they did not see the paper on the back of the door that was barely visible through the smoked glass

"Lounge closed for renovations, please use such and such a lounge at gate whatever"

On the way back a few days later I half expected them to still be standing there in line.

Some people just like to be in line waiting for people to open up. It's just their nature, and not just at airports.
