Unhappy with my tile job
The photos clearly show a terrible tile job. Tiles that are set crooked, tiles that are missing on the edge near the wall, grout lines of all different widths.

If the tiles were that uneven on the mesh then i would not have purchased them. If i were the tile setter and they were that crooked i would have brought it to the attention of the home owner prior to setting and made it clear that extra time would be needed to deal with an inferior product. 

If i had to set tile that were manufactured with such lack of uniformity and sloppiness ( and i am not sure i would even agree to ) I would have cut out the crooked ones and used spacers to insure straight tiles with even grout lines. If care and time were taken then they could have been set to look good but the installation cost would need to reflect the extra effort.   

IF the tile was that poorly set on the mesh then It sounds like you got a sub par product and tile setter who did not care to make it right.
