But did have some funny things happen there
During a visit to Sing with my mate , they had a serial hotel elevator pee'r in on the loose ..... so they set moisture sensors in the carpeting and an alarm rang in the security office
They caught him when he got to the main floor and it was headlines in the Straight Times
As to the Airport, on another trip alone mate noticed a grossly overweight and "unmistakable from behind" business friend from California at the Airport urinal so he stepped up beside him and said loadly "Chuck .. We really gotta stop meeting this way"
Chuck broke up and laughed so hard he pissed on his pants .. several local english speakers also broke up and in fact explained it all to those who missed it or didn't speak english . Fortunately Chuck saw the humor in it
Overall we were very uncomfortable in the clearly authoritarian city / country where the slightest misque or misinterpretation can be disastrous
