Why are people being ungenerous/make a big fuss just for a coin?

Here is the video showing that people who have given away their coins and expect to take it back. First of all, coins have minuscle value. Second, it’s shameless to want to take back what you have given to others. Third, it’s the result of your own decision so it’s better to gracefully accept the consequence instead of blaming that people have lied to you. Goodness, as if it’s not easier to just walk away and let it go.

I have many coins that I got from purchase exchanges and I would happilly give them away even without them asking. I wouldn’t want to be seen taking my coins back from the donation can after I put them in.
