Advice about a tile installation 600 x300 problems, help what do I do next?

sorry to say this but this is a very basic error by your tiler. anybody who is in the trade realises this issue when fixing in a brickbond pattern. a professional tiler would check for bowing by doing any of the above methods that have been mentioned.

I've had a couple of jobs recently that have had this issue.As soon as I see the tiles I do as Dave says and put them against each other,then inform the customer and say The only way I will do it is an a straight set.They've all looked good so far.
Was the tiler able to contact you during the day to tell you of the problem,if not he might of just thought he either looses a days work or does as you've asked.I'm not saying he's right at all but if I stopped work everytime I had a querie I'd get nothing done.
