This is the thread to ask real dumb questions as to why they don't build things the same way in Thailand as they do or you think they do in your home country, but I will be giving some examples....
Tiling, 95 percent of tiling in Thailand is on the floor, 95 percent of tiling in the UK is on the walls, 95 percent of floors in modern buildings in Thailand are concrete, in the UK they are wood, so we can see some major differences straight away.
The little crosses
These are used as spacers in the UK, it's a major breakthrough on using matches to space your wall tiles, in Thailand though all grade A tiles are exported so you will be left with grade B, these all have slight size variations, so why the fok do you think you can use normal spacers on tiles that have variations on their sizes? You can't, you got to balance the differences out to get it to look good.
Right, next question
