For the past years, I adhered to the belief that the reminders we repeatedly hear in MRT (stored value cards and exact fare available in Booth # 1, do not step on the yellow tiles, etc.) were recorded. Man, I was wrong!
Everything was usual. The walking people, the helpful reminder to step afar from the yellow tiles and me absent-mindedly waiting for the next ride. All of a sudden, I noticed that the "recording" was being played way too often. Then it came: a reminder delivered in a higher note as if the speaker were gritting her teeth. She was very aggravated to the point she stuttered in the middle in of her sentence in extreme resentment.
I stifled a giggle.
