Hey gas station owner, if you charge extra for credit/debit, you have lost my business

Several local gas stations have started charging anywhere from 3 cents to 10 cents more per gallon if you use a credit or debit card.  I understand the benefit of cash only sales to the vendor, using credit or debit benefits both the purchaser & the vendor.  The purchaser gets the convenience and the vendor gets increased sales. The cost to the vendor comes at the point of sale and the cost to the purchaser comes when they pay interest. These stations have decided to push their costs on to the purchasers; however, this is a bad business decision.  If they were the only station in town, or if all the others were adding this cost, I suppose they would not lose any business.  But there are many stations I can patronize, without going our of my way, that do not add this charge.
