Paying for gasoline at the pump may be convenient, but it can also be risky. Just a few days before Christmas, two customers of a local convenience store reported being victims of someone using a credit card skimmer. While the Bulloch County Sheriff’s Office posted a warning in its Facebook page, Capt. Todd Hutchens said no actual skimmer was found at the Zip-N-Go station on Hwy. 67 in Denmark, but that doesn’t mean it wasn’t there.
