Everyone in life makes mistakes, that's how you learn, I learn most days lol...it would seem, in this case, the tilers work has failed to satisfy the expectations of the customer however, on another day and another customer could pass as a good tiled job and the exchange of tilers sweat and customers money would have been good. In this case, its fair to say mistakes where made but the timing seems odd considering one bathroom has been done which must have been a good job or you wouldn't let him near another. Another thing, we have only seen 2 pictures of this work and numerous people are hanging the tiler.... I thought this was a "tilers" forum! ... All that needs to be said on this matter is 2 small rectifiable mistakes have been made based on the 2 pics, too much opinion regarding payment and career change imo
