The second impression of mine in Singapore was that there everything is prohibited.



among others:
- chewing gum (as they say because they wanna save the money of cleaning up)
- durian (since its very smelly on the MRT or at public places)
- playing football, riding bike, picnic or anything in parks or between the HDB houses
- parking in front of your house (you have to use the parking houses)
- pets almost everywhere



They take it very serious, you pay fine immediately if you break these rules. An order must be city which is very charming but very strict.
