Queuing at gas stations on the French border

We received images of a gas station in Nieuwkerke (Heuvelland) on the border with France. Many French people come to refuel there anyway, because the excise duties are higher there, but more compatriots are also refueling quickly, before diesel becomes significantly more expensive tomorrow. It takes a long time to wait. To give an idea: a full tank of 60 liters will be almost 9 euros more expensive.
