I have remarked that people from China always use the close door button. At first it weirded me out because I always waited for the door to close. In my apartment the close door button is a trap because one has to hold it during the whole closing door procedure and maybe 1 second more, otherwise the door will open. It usually results in more time lost than if one just waited for the door to close.
