I think the first thing I learned about durian is that it's banned in public spaces because of it's supposedly foul odor.
That's usually the first thing Westerners learn about durian. A fruit that is not allowed on buses, trains or in hotels has a certain shock factor, a fact that most journalists disclose in their "hook" or lead-in.
But how much trouble will you really get in for sneaking a little creamy fruit on the subway, a bus, or a hotel? I took the trouble to find out.
