I remember seeing signs that tells you that you could use your
handphone in that area and payphones & phonecards were so
common that you can see it in every corner.
I also have taken buses with those loud engines (replaced by
Scania N113 NAC), SBS and Trans-Island still have those "OMO"
(one-man-operation) and buses with sliding doors for the exit.
Woodlands used to have many different bus terminals all over.
Air-con double deckers did not exist then.
Kids used to have those tamaguchi, digimon and GameBoy devices
with each other a lot.
I still have my tamaguchi, 2 digimon. complete with the batt
tabs.
