The fines are real: gum, jaywalking, and eating on the MRT

Singapore's rules are enforced. No eating or drinking on trains and buses (not even water), no littering, no jaywalking, no smoking outside the marked areas, and chewing gum isn't sold. Vaping is illegal and devices are confiscated at the airport. Drug penalties are among the harshest in the world. None of this is a problem for a visitor who follows the signs, and the city is extremely safe in return.
