IllinoisGasPrices.com is showing a Shell station in Wheaton at $2.93 per gallon this morning, while right up the road a Citgo station is at $3.29. Wheaton is the only city listed on the "cheapest" and "most expensive" list this morning, and the $3.29 was spotted after the $2.93 was reported, so that excuse won't work.
Only one local station is listed, a Clark on Main St. in Creve Couer is "down" to $2.90. Still a buck too high, but getting there.
BTW, congrats to the lovely folks in Sesser and Christopher, IL, both just east of Duquoin and south of Mt. Vernon, for their concern for their customers. A station in Sesser leads the whole state at $3.59 per gallon, and the price at all four Christopher stations listed on the site is $3.29 per gallon. Way to go, guys!
Seriously, the best way to handle this is simple: Give them six hours to change the price, or be shut down for a week, BUT make them still pay the help their normal hours. Just like a ballplayer who cheats, you suspend 'em. Tell owners they have a choice...keep your fuel prices in line, or lose a week's work of receipts without losing the payroll.
