Been buying gas here for years. They just changed over to chip readers in their pumps, and since I've been noticing they will often give you Super gas (The most expensive) when you explicitly chose the cheapest gas. When you complain they will either tell you that you are wrong, or try to tell you that you must have pressed the wrong button by accident. Neither of those things are possible - the pump I used clearly said the cheapest was selected but the price was charging was for the most expensive, and I've been pressing the same button for years with no issue, until the new chip readers were installed.
