However, the fun began when I tried scanning my passport and
lo and behold, it does NOT work!
No matter how many times I switched between gates the first door just wouldn't open... So I gave up and joined the queue of shame, once I approached the IO I asked her what's going on and she replied "we discovered issues and had to 'rewrite' the entire software"... 
The problem is also the right hand does not know what the left hand is doing in Thailand.
