New Kitchen Floor - door join OK?

[AlexJ]

Hi,

Thanks in advance for any advice.
My kitchen has just been done by a guy who originally said he would bring in a specialist tiler but then just tiled it himself saying that the tiler was double booked. After tiling he removed the door and at that point chipped the tile in the doorway. When I asked about it he said that the bar that would go in the doorway would cover the chip. He put in teh rest of the Kitchen and has replaced the door and now I realise that he did not tile to the middle of the closed door and that a doorway bar will not cover the chip.
Also the new tile level is considerably higher than the old tile level.

My question is: What can I reasonably ask him to do to rectify the situation?

Not sure if this photo shows the issue well enough

install a transition bar that slight wider than the door. it wont look out of place, and from the photo i think it will only poke out 5-10mm. One the same colour as the tiles also will barely be noticeable.
