No fuel or no 95 unleaded

The Fourways Crossing service station had no 95 unleaded fuel last night. This is not the first time that I have had to go to another BP service station for 95 unleaded.<br> The Grosvenor Crossing service station is even worse. I have a 50/50 chance of them not having any fuel at all or no 95 unleaded when I stop to fill up late at night.<br> <br> I have never had to leave a Shell or Engen service station because of no fuel. So why are BP service stations regularly out of fuel? Is it a supply issue or are the service stations poorly managed?
