We left at TUAS via automated gate, easy and fast, but entering was a zoo via the manned gates (on a Monday evening, of all times) It took so long, that our bus left without us (note to self - never again 707!) so we had to take the shuttle to the MRT and the MRT downtown.
(as for gov't iris database of citizens - how do you spell "1984" in Singapore? /RANT)
