1. How about an easier way to get people out? Like a non-electricity-operated way of opening the train doors. Like a lever system or something. Even if only for a few doors per train.
2. Or a safer way to break certain windows meant to be broken in case of an emergency if that's possible. Like buses have it! That thing that's supposed to be a hammer to break the window but is so small and harmless-looking.
3. Even when you think a message is kind-of-private, the public eye is always ready to devour and criticise, especially if you're a big company that represents the government and take the people's money (and raise fares). Especially if you represent the government.
4. My brother offered a much more reasonable explanation for that 'income opportunity' alert to taxi drivers. See, taxi drivers would avoid a place that's said to be crowded, because there's bound to be a traffic jam, so 'income opportunity' is a way to bring them over, or any phrase that focuses more on the money than on the potential congestion. After all, they're at work; they're looking for business, not inconvenience.
5. Making the top person step down might not even make any difference really aiyoh it's such a huge company, the top person isn't always at fault with every single detail. And the person responsible for whatever there is to be responsible for (that 'income opportunity' message, I guess) has probably already learnt his/her lesson well from this incident.
And how is stepping down taking responsibility!?!?!?!?!?!?!?!?!?! That's AVOIDING responsibility!!!!! The right thing to do would be to wipe away the tears and get down to work resolving all the problems and ensuring minimal chance of these happening again, not step down, so people should stop unnecessarily suggesting that top people 'step down'. In fact, not stepping down is harder, because it's facing up to the mistakes and the humiliation and criticism and taking it in your stride. Yes, they have a huge pay and yes there's a mistake that they need to account for, but that phrase gets annoying when it's used unnecessarily.
