Why do people despise weakness?

Today, a cashier gave me a dirty coin. At the first place I didn’t realize it was very dirty. The dirty covered almost all over the places. So, now I can’t give it to anyone without cleaning it. I am sure no one will accept it. Anyway! The reason why she gave it to me had a lot of things to do with weakness. Let me explain. I am on abroad. She realized I was stranger/foreigner/whatever-hell. So, even if I had realized, there wouldn’t have been any change. She knew I wouldn’t be able to confront her. People not only despise or demonize weak, they also exploit the weak.

After the realization of dirty coin, I went back to there. I felt so sorry about myself* that I couldn’t confront her, couldn’t say anything to her. I sat down. Just watched her how she treated other costumers. She was greeting other costumers with a big smile. 100% of other costumers get the same big smile. Because none of them were stranger/foreigner as I am. I got a dirty 2€ and and no greeting.

Just a silly example from real life. Choice to believe my story is yours.

*to be honest, I sometimes over-dramatize myself. I actually laughed at what I wrote when proof-reading. But it’s completely true I felt so sorry about myself. The realization of the fact that everyone was trying to find a way to fuck me up, exploit me… devastating.
