- AAAndre AloFeb 9, 20265.0I got a snack from the Sinclair Gas Station. Also someone told me to give them a snack. He was a older African man. And he told me that he was staying at the Motel 6, across the street.
- LTLeslie TorresJan 11, 20261.0DONT USE YOUR CREDIT CARD HERE!! I’ve seen so many other reviews of the same happening to other people i was almost charged 150 dollars on a pump tonight before even putting any gas in my tank caught it and declined it. mind you my car only takes 50 for a full tank so 150 would be impossible of an amount to need for my vehicle. Please investigate this gas station and stop these skimming scams ripping innocent people off
