I'd be more concerned with the lack of adhesive on the edge of the tiles in picture 3.
The tiles in pic 3 are small cuttings 30cm x 10cm; overall i am satisfied that the application of Tiles has been fine ie generous Bed of adhesive plus back buttering.
I have been constantly observing the Tiling and providing positive feedback the only regret I have is that I did watch him do the grouting. So to some extent I blame myself. But it's a lesson learnt.
I will not repeat this mistake when i get the kitchen done

Is this the same tiler that you had concerns with regarding the corners last week? Have you spoken to the tiler about this? I am concerned that you have so many questions regarding his working practices yet he is now nearly finished.
Yes this is the same Tiler; overall he is good but there are certain practices that conflict with what I have come across here for instance he was insisting on grouting corners and change of planes; so I sought advice here and the consensus was to Silicon those areas. I spoke to him and we agreed to Silicon.
I also thought that the spacing size in corners varied a little bit so I sought advice here and was assured that though they were not perfect, they were fine and the bead of Silicon would conceal any minor deviations.
Having seen pictures on sites like Houzz and observed the degree of professionalism here, it is no surprize my expectations are now very high.
May be I am expecting TOO MUCH after all the grout spacing is 1mm. How can anyone be expected to fill that in all the way using the approved grout float application technique?
My first port of call has always been to seek advice here, not only has it benefitted me immensely but hopefully the threads I have created may assist someone else.
On face value the work I have seen meets my expectations, only time will tell.
The works I have had done is by a Building company; Choice of Substrate, preparation and Tiling was the key for me. As regards to Plumbing, Joinery, Electrics, Plastering I have no issues.
Like Gas Safe I think all professional Tilers should be regulated by a body and be subjected to refresher courses even if it is just one day a year.
