Well it would depend whether that door is pushed open or pulled open..if it’s pulled open, surely the rug would be annoying to have there, but if it was pushed open then the rug wouldn’t get caught underneath the door all the time. Most doors are pulled open though aren’t they….???????
Oh i just realised the door is open on 2 of the pics and it is quite clearly pushed open………………………………..keep the rug,
