Unfortunately, that danger does not seem to be a factor in the town as it is a very safe area. The one thing that could come into play is that the cheap gas station is smaller (so you often have to wait for 1 or 2 cars) as well as on more of an obscure corner, as opposed to the bigger gas station on the main road. But I still wasn’t sure that was enough of an explanation for a 40 – 60 cent difference.
Also, is it even possible for people to arbitrage gasoline like that? I suppose speculators could, but they don’t normally go to local gas stations and just start buying up their gas, right?
