The Singapore Police Force arrested a man at Changi airport for buying a plane ticket just to walk his wife to the gate and say goodbye. He apparently had no intention of flying anywhere. It does sound like a lovely airport to visit but I hope he purchased a fully-refundable ticket. From CNN:
Anyone accessing the gate-side areas at Changi without intending to fly can be prosecuted under Singapore's Infrastructure Protection Act and fined up to S$20,000 (US$14,300) or imprisoned for up to two years. Thirty three people have been arrested under the legislation in the first eight months of 2019…When Changi's new Jewel terminal opened in April, it made headlines around the globe for its 40-meter waterfall (the world's largest indoor one), a 14,000-square-meter Canopy Park, complete with a suspension bridge, topiary and mazes, and one of Asia's largest indoor gardens with 3,000 trees and 60,000 shrubs.
