When the gas station or gas station chain (more likely a chain than a sole proprietor) calls up for a new delivery (and it’s most likely that the new delivery is on auto-delivery; the fuel wholesaler wants the gas station’s tanks full, not its tanks full), they change the price at the pump to the higher price.
When the gas station chain learns of the new, HIGHER price, it jumps the price at the pump.
Been that way since at least the first 1970’s gas crisis.
Most fuel wholesalers aren’t making bank in a time of chaos. These aren’t international conglomerates. The sole proprietor gas station is GETTYing fucked. The gas station chain is on tight margins.
Are Big Oil companies making bank in this chaotic mess? No clue.
Trump minions are.
