If gas prices drop suddenly and a station is forced to lower prices to sell the gas they already have in their tanks because a bigger station across the street or nearby emptied their tanks sooner and can sell the less expensive gas sooner, of course it hurts a mom and pop who is selling their gas at very low margins to begin with.
They can either lower their prices to compete, losing money on the gas in order to keep the sales coming in for the store items or keep the gas price higher so as not to lose money on the gas they already bought causing them to lose money on the store items because people will go for the cheaper gas and not stop at two different places for gas and milk.
Fox wasn’t wrong about the mom and pops but they didn’t go into that detail they just wanted to blame Biden for something else.
They could have gone into detail about how gas prices work and how the market being so volatile or controlled by speculators only hurts small business. But then they would be forced to explain that a president can’t or never has controlled gas prices.
