I was traveling from Singapore to Houston and had a brief stopover. The terminal was very crowded and there was no place to sit/rest or what so ever. After a 10 hour flight from Singapore to Moscow we were exhausted. Then we had to stand in line for more than half an hour in security check up. The officers at the security were rude and didn't speak much English (what they said was barely comprehensible and some didn't speak at all - only gestures and bad attitude). After the tiring security checkup we headed for the restrooms which was crowded and didn't allow any personal space at all. Then there was no place to sit till your gate opened because it was very crowded.
