Guys
many many thanks for the advice and support, had a **** day,
today i went in and had a chat with the customer and told him i was not happy with the lipped tiles, he agreed and i took them off, i had to smash loads of plaster and cut the angle beads out to try and get the corner straight, he has only just had this plasterered and he is gonna kill the plasterer, put another day on to the job but i want to get it the best i can for him,
I have learnt so much and its not over yet,
Once again thank you all for your time
