Morality Question: Am I being an ass?

[theGinsue]

Those Circle K/Kum & Go/7-11, etc typically aren't owned by the employees or even the station manager. Same thing at the grocery store and the online firearm/reloading parts providers. Many of those places will charge the employee for the error either in direct loss values or in fines. One persons mistake could be the difference in whether or not they've got enough money to pay their bills this month.

People make mistakes. The moral and just thing to do when we realize this is to let them know about it to give them a chance to correct the mistake. Taking advantage of those mistakes isn't the right thing to do, regardless of the advantage we may gain from it. I think one of he biggest problems in our world today is how every mistake is exploited for personal gain, with zero consideration for the one who made the mistake.

...Taking advantage of those mistakes isn't the right thing to do...

If you know about it and take advantage of it, it is theft.
