There’s a BP fuel terminal near me. The gas comes in by way of an underground pipeline and trucks from a bunch of different companies buy the gas for distribution to gas stations around the area.
In other words, boycotting BP stations only harms cashiers but people are buying the same gas when they “stick it to the man” by filling up across the street.
—yep—it’s like that thing that wandered around the Internet for years about “everybody boycott Exxon for a day”—
