Had a lady waiting on hair products one time. The genius decided to start her hair that day BEFORE I delivered the rest of the necessary product needed to complete the job. Problem was her bell was broken at her Apt Complex, so I left a delivery notice and left. She started calling the Center flipping out on the OMS girls, and then my center manager. After about the 30th call my center manager calls me and asks me to do him a favor and go back. He wasn't instructing me, but said "Can you please go back? This lady won't stop calling and cursing the girls out". OK, sure, no problem. He tells me that I need to walk down the left side of the building to the side steps, and knock on the first window to the right of the door because her bell was broken. I go back, knock on the window, and immediately hear "Finally motherfu*ker! I'll be right there you fu*ker!" Great, now I'm anticipating a screaming match, and I was correct. She opens the door and starts screaming at me. I calmly say "Ma'am, I was here earlier and rang your bell..." she cuts me off and screams "MY FU*KING BELL IS BROKEN!!!!!" "OK ma'am, now how am I suppose to know that? You didn't put a note on the front door telling anyone that your door was broken, so how would I or anyone else know?" "JUST GIVE ME MY FU*KING STUFF!" No problem. I hand her the box, and then the DIAD and tell her to sign. Soon as she finishes signing she throws the DIAD pen at me striking me just below the eye. I mean just below to where a centimeter more and I'm stabbed in the eye. I lost it. I started screaming at her and threatening to call the Police. I told her NEVER use my company again because she'll NEVER get another delivery from me. Ignorant POS almost put a hole in my eye because she was too fu*king stupid to leave a note on the front of her Apt Complex with instructions on how to reach her since her bell was broken and she knew it!
