If he thinks he can't make any money off that gas or he might lose costumers maybe, he shouldn't buy it? (they claim they don't make much anyway)
When the news gets back to the corporate official that Ahmed, the station owner, doesn't want his overpriced gas load, then we'll see if the price remains overly high.
Yes, I realize the distributor will find someone, somewhere to buy his overpriced gas (hopefully at great expense) but, Ahmed won't lose any costumers who might think he's trying to get over on them.
Supply and demand works both ways.
You and Ahmed are perfectly free to act as you suggest.
And I assure you that, if enough people did this, the price would go down.
Amazing how that works...
