I thought u were a scientist not semanticist!
That reply makes u sound quite arrogant to be honest.
So if I followed your RECOMMENDATION and it went belly up, do you really think the client would accept my excuse of "I'm sorry Mrs ****** but some guy I've never met who lives on the other side of the world who hides behind word play told me to do it!" Hahaha yeah ok, like I'm that unintelligent!
All I was looking for was for you to give an example so that I could make an informed decision of my own, and not one that I'm being forced to make, as you seem to suggest!
So in view of the fact that you are neither the stone supplier, the client nor building contractor, and are completely unwilling to offer a 'suggestion' in how to deal with my particular stone, how do you expect a mere uneducated tiler like me to take up your theories?
