When driving through Barstow California, don't get gas at the Chevron on Barstow Rd Exit, it's 60 cents a gallon more than the Valejo station across the overpass... that is 12 dollars more for 20 gallons, wasted

 I've posted before that I believe that some gas stations change the prices highest left to right to get you to accidentally buy the most expensive gas  http://justacarguy.blogspot.com/2011/09/do-some-gas-stations-try-to-trick-you.html
above are the reversed from normal levels of price gouging at the Chevron, and below, in the normal arrangement, is the Valejo gas station prices
