Not a fairy tale

WTF IS THIS?! So you can eat medicine, but not sweet? And the ironic thing is... Definition of drugs, is that when absorbed into the body of a living organism, alters normal bodily function. If a sweet is able to let this poor lady here curb her motion sickness, prevent herself from vomiting, making a mess on the train in which will post a scene to all passengers who saw it, to the cleaners who will have to clean it later, why the hell not? Nothing is perfect. The person had a point, people will follow suit when he close an eye for this poor lady with motion sickness. But... The point of banning food and drinks, is so that there will be no littering, and no dirtiness, no smell. Right? But a harmless sweet, other than the littering part, shouldn't make such a big mess? What if people of the public are able to dispose of their rubbish well, will it still be banned? What if there's rubbish bins easily accessible at train stations, or even platforms, will it be better?

Yizhan told me that medicine is allowed, but I'm not sure if plain water is. I mean... Plain water should be accepted right? It's not some sweet drink like bandung or what, which will make a mess once spilled, and attract ants? This is some bullshit :/
