I am very annoyed with my mail person. He writes on my mail and never delivers it and lies.
I have an older mailman...around 40 and he is the kind here and he constantly writes on my mail and doesn't deliver it.

Is he bad at his job or hitting on you?
assistant
He thinks he is the king*. He is very bad. My mailbox is on the outside of my fence but he writes "dogs" on it..won't deliver it and also he throws my packages to wreck them. Post office thinks he is great and won't do anything about it.

Make him Facebook famous. The Viral terrible mail man.

I know! I just got cameras for that except I never have packages delivered here anymore because of him.
user
Send you self a empty package or something.
