Singapore is an interesting place. Inside a subway train and outside a subway station, you find how much you should pay fine when behaving inappropriate. You should pay S$500 if you eat or drink inside the car, you pay S$1000 if you smoke, and you pay S$5000 If you play with flammable goods. Then, what happens if you eat durians? When people read three sets of NO signs and fines, do they follow the last NO sign without thinking its fine?
