Wondered when Ho Chi Minh would crop up!
Awful place. I saw a woman seriously injured after she fell on an escalator. She was trapped at the bottom but the thing just kept dumping other passengers on top of her -- there were no emergency switches.
In the end there was a whole heaving mass of humanity at the bottom of it and several others, mainly elderly, were hurt as well. I managed to escape the melee by vaulting over the side and descending the last eight or nine feet down a bit more quickly than usual.
Oh, and immigration are corrupt as well. Make sure you take a load of passport size photos with you, even though you don't officially need them.
