Take it easy Varley old son, sorry if my comments ruffled afew feathers, yours or anyone elses. But Crocotile raised a few pointers that I thoroughly agree with, and I'm entitled to an opinion like anyone else,even tho' you don't agree with it.
Let me first of all deal with that caustic little barb you threw at me. No it was not "a little bit of a contradiction", and yes even after 20 odd yrs in the business. Unlike you, I'm still not too proud to say I'm still learning. Do you honestly regard yourself as being so good at what you do, that there is no more to learn? If you do, then you are saddly deluded, surely. EVEN A MASTER CAN LEARN FROM NOVICE!......
Allow me to clarify my point. I hold a C&G qualification in Bricklaying gained back in the 60s after a 5yr Apprenticeship. Back then, if a "Trade" was not preceded by a 5yr Apprenticeship, it was not regarded as a Trade. Any skilled job requiring anything less than 5yrs training was classed as Semi Skilled. And Tiling came under that category. I'm sorry but thats a fact. And for you to assume that you can impart Knowledge that I don't have, even tho' you don't know me or my circumstances, And all because you've done a short course, is nothing short of bare faced arrogance
