Question. You hot int a store. Approach the self serving u-scam

No one is in line or in the store. The previous person. Left 10 dollars in the machine. What do you do?

If someone is there I say point it out they left it but once they are gone and you did not see them.

Do you tell the cashier who is going to pocket it?

What say you?
"it takes a wise man to know when he is in error and a noble man to admit to it"
