- PJPamela JenkinsMar 19, 20261.0Worst customer service in the world!!!! They will never again get my business!!
- KAKaia A.Dec 7, 20251.0If I could give zero stars, I would. I’m a Wyoming resident, and my commercial livestock transporter had to pass through Casper during this week’s storm and road closures. She stopped at this Sinclair on the south side of town. She identified herself as a commercial transporter hauling livestock for a Wyoming resident and requested access to a standard hydrant/hose point- basic support that long-haul drivers routinely receive across the region. This location refused outright because she was not a Wyoming resident. For a station positioned in the middle of Wyoming’s livestock corridor, that’s a significant operational failure. Drivers hauling live animals rely on minimal cooperation from fuel stops, especially during winter closures, and most places understand the stakes. Even a hotel in town stepped up when this station would not. If you’re a livestock hauler, commercial driver, or anyone traveling with animals, be aware that this location did not provide even standard courtesy or support during severe conditions. There are far more reliable stops in the area. I recommend planning around this one.
