Singapore is known locally as fine city. There's a fine of $500 for smoking in public places such as cinemas, trains, lifts, air-conditioned restaurants and shopping malls, and one-off $50 fine for "jaywalking"- crossing a main road within 50m of a pedestrian crossing or bridge. Littering carries a $1000 fine, with offenders now issued Corrective work orders and forced to do litter-picking duty; eating and drinking in the MRT could cost you $500. Other fines include those for urinating in lifts(legend has it that some lifts are fitted with urine deteectors), not flushing a public toilet and chewing gum( which is outlawed in singapore).
Temperatures are uniformly high throughout the year, but it's the region's humidity levels that make the heat really unconfortable.
