Crowded Don Mueang Airport has a safety problem 

The hall was crowded, with several very long queues snaking out into the public concourse. It was impossible to work out where the lines began and ended. 
I saw three different puddles of urine on the floor where people had no choice but to go, as you would never catch your flight if you left the impenetrable crowd. The floors had become sticky with urine being walked throughout. People were surging and ducking under ropes to queue-jump as they panicked about their flights boarding. 
The problem here is not merely one of “service” but also of the security and safety risks of so many people being jammed into that airport area.
