That looks like the tile work in Latin America. You cannot believe the crap work they all do. They start at one wall and work to the next rather than starting in the center so that the edges are even all around. Cement block work in Panama is the worst I have ever seen. They leave gaps in the blocks that you can literally see through, put your fist through. They drop a block and it break, no problem use the pieces in the wall then fill the cracks with crumpled up cement bags before the top coat of cement goes on.
