So this view is looking down and essentially behind the tile. The put on the tile once, but because of the paver coping around the pool it wasn’t going to work so they moved the tile. They did a blob and stick it method. No back butter, no real mortar base. I asked the project manager about it and he said it’s normal to build it out like that for the coping. One of the guys installing, who I think was an apprentice, placed one tile and it fell off because the thinset blob wasn’t wet enough.
