Diamond Shamrock in Westminster (6990 Federal Blvd)

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.

This place has everything you need on your way to work

Hard to understand cashier

Great customer service.. unknown hours

Hard to get to
