Maintenance man almost got himself killed
To preface this, Texas has castle law, and if someone I don't know is in my home uninvited and unannounced, there's a 99.9% chance that they will be shot before questions are asked.
I'm sitting on the couch watching TV, and my door opens. I always keep it locked, but I've picked locks before and it takes all of 30 seconds to pick a home deadbolt. I don't trust anyone. There was no knock at the door or anything. It just opens, and I see a man's hand on the knob. I draw my gun, which is on my hip, and the man crosses the threshold. He's a Mexican in grey sweats and a beanie. I looked at his hands, which were empty, so I held off on pulling the trigger, and he says "Maintenance". I paused, told him not to move, saw he had a key, but the no tools part kind of made me confused, and I'm not going to trust his word. He has no uniform, badge, or anything else identifying him as a maintenance man. I call the apartment complex and ask if they sent anyone over, since I had nothing scheduled. They said they had sent him over to check on something with the air conditioners and apologized for his entering without knocking or announcing himself. I explained that it had almost cost him his life, and recommended they also get badges or uniforms for their maintainers, as well as give the tenants a courtesy call.
I'm glad I didn't pull the trigger, as he was innocent, but I'm also glad that I was aware, had my gun on my hip (even though I was at home), and had it drawn before he could even get in. By the look on the man's face, I'm pretty sure he had learned his lesson. He didn't speak much English, but I explained to him that he needs to be more careful.
