The metro trains are playing text announcements saying that begging is illegal (!) and if you really want to donate money, it's better to give it to a charity fund—that way you won't break the law and the money will be spent more wisely.

Plus, it's absolutely freezing in the metro cars. The air conditioning is working overtime. Except they only have it on the trains. At the stations, it's the opposite: unbearably hot and stuffy. You'd think you need fans just to survive. Even at night. And there are always plenty of homeless people around.
