Why the truth is not in them ??

I believe most people are honest and show at least some level of empathy. We help each other to achieve better things.

Then there are few people who do not look at you as a person but rather as a mark/asset ready to be exploited. They even come with silver tongues, masters at lies and deception. Sometimes you’ll find many with a short period of time. But don’t make the mistake of assuming this represents people as a whole - don’t let these few self centered people define your world view.

There is absolutely no benefit from stressing about it so don’t. All we can do is plan and screen the best that we can then sometimes roll the dice. Most/all of us have been fooled/snookered at least sometime, and chances are it may happen again. Don’t beat yourself up either. Don’t live in paranoid fear.

It’s easy to get angry when somebody wrongs you, but I try to understand the root cause to better to deal with them and is better for my mental health. I look at the world as endless potential wealth. If we came from huts, clubs, caves, where did all this stuff we enjoy come from? But some people look at the world as having limited pie slices, so they better hustle to get theirs before someone else, sometimes using decent. Often they think in terms of lack, glass half empty than half full. Something in their life programmed them to think this way, often negative.

While there’s been a few practical advice posts regarding the OP, there’s been much debate on the morality aspect. Although many valid points were made, I think the expectations are unrealistic and focus is wrong/unhealthy.

Seller risk is a fact.
My past retail experience at Sears Catalog exposed me to many customer abuses. Some tried to return abused/used items, even tried to cash in on non-Sears items and failed homemade rewired equipment. This is just a small typical example on what happens to sellers as a whole.

So how long has this gaming by customers been going on?
Answer: since mankind has started trading/bartering/buying/selling. Sellers/retailers know and accept this risk because like the sun rises and the sky is blue, this is just an unavoidable fact.
What’s going on is that a few non- professional/low-experienced new sellers are unrealistically dismissing/ignoring this risk, then they’re surprised/disappointed when something negative happens to “them”.

Mankind is imperfect is a fact.
Mankind is driven by both selfish and social needs. Sometimes these needs are at odds with each other. It’s quite easy to criticize someone who acted against social norms for selfish reasons, logically arguing point by point. But a better question is how is this serving me and/or others? Is it making a difference?

Taking a magnifying glass and bitching about another’s actions/shortcomings bears little/no fruit, and runs the risk of unrealistically coloring your world to the negative. Is it going to change the individual, society, or anything?- I’d say no. Would things change if I recruited people to my anger/pity party where we can bitch together?-Again I’d say no. Can habitual thinking about the shortcomings of people negative skew your perception vs reality? A Big Yes! Some people go they life habitually asking what’s wrong with x,y,z. Similarly some people habitually look for offense from others. These tinted lenses, often driven by some underlying fear, does indeed affect how the person interacts/communicates with others.

Bottom line: it’s unwise to spend your limited time and emotions on a fruitless endeavor especially one that has the potential for negative lasting consequences.
