The most ethical action for Eddie is to: b. inform the waitress of her over payment.
Explanation:
Generally people enjoy having food at the restaurant. After having the good food we pay the bill and leave the restaurant happily. Sometimes after paying the bill we may get additional change for the bill amount paid. Some of them may leave the restaurant with the extra money. But this is not ethical.
In the above scenario, Eddie pays $10 for her bill of $8. She received $12 back instead of $2. It is good to inform the waitress of her over payment. This will show Eddie as more ethical.
