If I recall, in the Singapore subway, there's a fine of 5,000 SGD (?) for bringing durian? Yeah, I can't deal with the taste or smell of durian, though shockingly my youngest daughter loves it. No idea how that happened but she was going crazy over them at one of those street vendors where it's served fresh and chopped up right in front of you. I had to walk away at least 20 yards to keep from getting nauseated by the odor.
