Went to the ATM to make a withdrawal. Someone accidentally forgot to take out their debit card out the machine. I currently have her card. Now I don’t know if I should go into the bank and have them call her and say I found her card, or it’s too late and she already canceled it. 🫤

I’m leaning towards option B…

You could call the bank and ask what they'd like you to do with it and if it's worthwhile to go there and turn it in.
