By being an absent-minded schmuck monkey, that’s how.
You know how you can opt for “cash back” when you use your debit card at the supermarket? I needed some cash so I could use the vending machines at work the other day, so I punched in for $10, took my receipt and groceries, then walked out. And completely forgot to take my $10.
And of course I don’t realize this until hours later too, so no chance of going back and retrieving it either.
This wouldn’t be so bad… except that today I did it AGAIN, opting for $10 cash back and then once again completely forgetting to take it. 
I hope whoever ended up with my money got a good meal out of it at least.
