    🇺🇸 Employees are friendly.

    Price on the digital SIGN is pre-war and WRONG (too low). Remote control is likely broken, and glass on sign is broken. Not a good look for a Dallas HQ co: NYSE:DINO.

    HOWEVER… current price is still much lower than anything north of the border 🇺🇸🇨🇦

    Its nice to have a convenience store and gas station near the US Border so I stopped by at around 8AM for a gas refill but my concern was the pump was running so slow. So I decided not to get a full tank anymore and thinking to have it done at Great Falls, Montana.
