Make Yourself At Home
Seeing people laying around on the floor in an airport might be slightly weird to look at, but it is actually fairly frequent. Between flight cancellations and delays, seats in the airport can be hard to come by, so in many cases, you need to improvise. This one appears particularly odd because the sleepy man is resting in the center of check-in while others are standing regularly around him. Maybe try to locate a peaceful area next time?
