You have no right to yell at me

I don't like to be yelled at. When I was a younger man, yelling at me, resulted in people getting their teeth knocked down their throat. But I am older and much calmer than I was when I was nineteen or twenty, but I still don't like it.When you yell at me.

I am a security guard. My job is to keep the staff safe at this facility. I worked hard to get into the field. I am in today and suffered many years as a corrections, officer. Today, we had a small incident where the covering of a thermostat was damaged by a person. So my technically my superior but technically not my superior tells me the security guard to go downstairs and get a specific screwdriver that I have no idea where it is and I have no idea what it looks like because I am a security guard, not the maintenance department. He is the maintenance department's boss, not mine but our boss lets him tell us what to do. I go down I find what I think is the correct thing and bring it to him and he screams at me that I didn't listen because it was the wrong one.

Like motherfucker, do you realize who you're talking too? You're not my boss!
