is it safe to live in condos in bangkok?
although you can make a thin mold/shell, then put something stiffer behind it after setting to act as a mother mold .
This happen often on the subway and elevated stations. Even in similar cases happens when someone hold the door for someone almost there. What really happens on this situation is that the train gets behind the schedule. For holding the doors, I say you just can get a verbal warning, but not going to jail. You can go to jail for something else serious, example, breaking anything from the train (window) or probably by pulling the emergency brake which is unlawful if it is not an emergency.
