Diamond Shamrock in Westminster (6990 Federal Blvd)

good location for gas and snacks

This place has everything you need on your way to work

This is by far the worst experience Ive ever had at a gas station. The woman running the register who claimed to be the manager was unprofessional and disrespectful. She called me derogatory racial slurs and tried to argue with me while assisting another customer.

Hard to understand cashier

Nice new place.
