Pathetic, Uncultured Sg Men (Single or Attached or Married) do not:

Let the lady enter or exit from a lift or the MRT Train. They simply cheong (rush) to go in and rush to go out;

Hold the lift door for all the ladies to exit from the lift first. They cheong out before you could say "Tsk!"

Open a door for a lady; If they do reach the door first, they push the glass door open and let it swing back, oblivious to the person behind them, lady or man.
