While the robber was unintelligible on account of his face covering, Brian told KSAZ-TV that "he didn't need to say anything."
"The moment he pointed the gun at me, it was pretty obvious what he was there for," the clerk told the station.
When the suspect took aim at a customer, Brian reckoned it was pretty obvious what he in turn had to do.
"I had the opening to pull my gun and shoot," the clerk told KPNX. "That's pretty much the whole thing."
Brian elsewhere underscored that he has long trained with a gun.
According to police, the "suspect became distracted by another person in the store and the store employee took the opportunity to pull out and use his own firearm, shooting and injuring the suspect."
"I'm not happy I had to shoot him, but I'm not stressing. The moment he pulled the gun on me he set the situation and I just followed it. He made the situation what it was," added Brian.
An employee told the Arizona Republic that "everybody is fine," except, of course, for the suspect who was taken to a hospital in critical condition.
Brian will reportedly not be charged for restoring order at dawn.
Despite this outcome, Joshua Black, an employment attorney, suggested to AZ Family, "My advice would be to someone working at a gas station would be, do not carry a gun. Do not bring a gun. There is nothing at that job that is worth risking your life."
There is no shortage of robbery survivors who might feel compelled to discount Black's recommendation.
A clerk at Blackhawks Tobacco & Vape in Rock Island, Illinois, was reportedly confronted by three robbery suspects Tuesday night, one of whom threatened him and his customers with a gun.
When one of the robbers allegedly took aim at a customer, the clerk readied his firearm and "emptied the magazine" into the suspect. No innocents perished in the incident.
TheBlaze reported in July that a female clerk in Texas was reportedly robbed and attacked by a knife-wielding suspect. Owing to the clerk's quick thinking, she survived with only minor injuries, having shot the robber, who was later taken to an area hospital with serious injuries.
Extra to those Black's recommendation may not resonate with, there are also unarmed robbery victims who might have otherwise benefitted from firepower like Brian's.
For instance, a 67-year-old Exxon gas station clerk working the graveyard shift in northeast Philadelphia was fatally gunned down earlier this week during a similar robbery.
