Actually, yes. Why do you ask? The point of sharing was that sometimes flukes happen. You couldn't tell the case was empty by holding it.
To me, it's not worth it to insult someone over a $20 item unless there some other fraud alerts going on. I value my reputation too much, and I am fanatical about providing a good customer experience.
Now if it was a $200 item, then my opinion might change a bit but my perspective would still be how can I make this better as opposed to how can I catch you in a lie.
That's just me.
