In Southeast Asia, ‘No Durian in…’ sign is everywhere. In a subway, taxi, hotel room and various other places. At first that was little odd. I understand ‘no food’ policy but ‘no durian’ policy? But after I smell durian in the street of Singapore, I totally got the point. So yes. I understand. No durian inside rule is legitimate. It could freak people out. I witnessed it. I should make a sign by myself and put that infront of the office building says ‘No Durian and No Show off’.
