While delivering to a house earlier I saw something in the bushes. Walked back to my truck to grab my phone to take a picture. As I was walking back to the bush the lady stepped out and asked me what was wrong. I told her, "nothing, I just wanted to take a picture of this rat snake in your bush." No sooner did the S in snake come out of my mouth, she back stepped into her house and said there was no way she was coming back out and would get the packages later. Didn't matter that I told her he was harmless. He was between 4'-5' long.
