There is much wisdom in what you have posted here today @ogochukwu, this specifically "strikes a chord";

or that they are passing through some Major issues in their Life and they are just transferring the aggression.

I learned this lesson early on in my career as a small town pharmacy owner.

I had a lady, new customer that was just plain rude, telling me to hurry up and I was thinking, "Man, if I can get her out of here, I will be happy if she never comes back. It turned out that her husband had a Major heart attack and had almost died. She was passing that aggression on to me.
She later came back and became a regular customer of mine and she was the sweetest lady you could imagine. I cried when she passed away.

Thanks for the post.
