Ah so the oil companies approached the advertisers and were like boy have we got an idea? All gas stations are not multi billion dollar companies lol, the last two local ones i saw change hands went for under $1M and they have local owners, only one had ads, and it was part of the new owners upgrades… so like that was a member of my community who replaced gas tanks to sell ads. It’s clearly worth some money, and was not forced upon them.
