The effective price calculation takes place directly at the cashier, of where from the paid quantity for the gasoline pump is released. That then however this quantity runs inevitably from the hose, is exactly the same nonsense (with really old technology at initial Soviet times that perhaps may have been like that, but nowadays the operation of the trunk is working like in Western countries) as that the necessary quantity must be estimated exactly in advance (one can deposit a larger amount at the cashier and come back for the change, or also in iterative approach again and again pay and refuel an additional (half) liter). And the conversion to "fill first, pay afterwards" is in full swing (although still far from being completed everywhere). The credit card symbols, however, have here merely a decorative shape, but apart from that the Belarus are quite habitual with foreigners and their currencies, as one can see here at the price list - a liter of premium gasoline for 80 cents, roughly half of the price of home :-) whereas in Russia almost nothing else is accepted beyond Russian rubles in cash.
