I'm surprised! I've always thought Singapore was extremely clean and had very strict rules about it.ignoramus said:
Yeah, I was truly surprised when I saw this when I went back to Taiwan in 2004. The last time I went back to Taiwan, which was in 1997, I didn't recall seeing this, at least not in such a consistant manner.ignoramus said:

I was really proud of Taiwan regarding this as even in the U.S., you'd often see rude people who would stand right in the middle of the escalators and block people who are in a hurry or sometimes two friends would stand side-by-side chatting away while blocking the whole traffic...
I've never encountered this, but then I don't chew gum. But this is good news for me as I hate gum and have stepped on them one too many time simply because the chewer was too lazy to throw it away properly here in the U.S. I also get annoyed when people "pop" their gum. This is the reason why I've always liked Singapore for its strict rules against gumignoramus said:
