In reply to The Lemming:
Couple of points:-
1. that fact that some one in the party managed to work a phone & ask for help means that either one person wasn't trying hard enough, or was the "sober safe nominated driver".
2. We are unusual in the world by having free MRT. In other parts of the world you either die or have to pay up, so people then think twice before setting out.
Maybe this is the problem, people just shrug shoulders & go "oh well MRT will taxi us home for free"....abuse of the system, like various other free systems/handouts in the UK, nice ideas, but now totally overloaded with requests from muppets...
