That would only need to be explained to a total idiot, along with the price at the pump, affecting shipping cost, with end user consumer paying more for anything purchased. Outside of TH, and other countries that don't allow diesel price gouging, sort of. Why TH freezes diesel price, and offsets the cost (petrol fund loss) on other petrol. Let those that don't conserve, who can afford it, to replenish that fund. Very smart move, and keeps 'across the board inflation' down. Socialism & democracy, working together, go figure. Some countries. like USA, need to take notice, but a subject for another day, another thread. You assume people are that stupid, they can't think for themselves. OK, I do also at times, but this one is too easy.
