Gas stations make very little margins selling gas/fuel ~2%. However, their own convenience stores have very good margins. So, a gas station operator would like to keep you at the station for as long as they can in the hope that you'll enter the convenience store. That's partly why they have restrooms, smoking zones(for countries where public smoking is illegal), etc. They are partly their for your own convenience and partly to make you stick around and eventually enter the convenience store. EV charging presents a perfect opportunity to keep you at their station longer. Each charge is probably going to take a minimum of ~30mins; and you'll spend most of it lazing around the convenience store drinking crap coffee marked up at 60%
