How block makers can rip you off

Just when you thought you have heard it all, when you thought you have seen every possible way you could be cheated while you build your house or manage a building project, then comes this. The measure ment of a block is supposed to be 225x225mm in height and width, but imagine a situation whereby your block maker is making blocks of only 200mm height? This is pure cheating, do you know the effect of this? You lay a block line of 9 blocks and get the height of 8! You have been scammed of 1 block in 9. Be guided.
