I have read literature about us receiving a fee for each transaction made and do not understand what that means. I do not believe we would want to charge our customers for using our ATM machine. Out of curiosity, what is the norm in our industry, which is the metal recycling scrap yard?

No, in the scrap industry, companies typically do not charge a transaction fee. Remember, your ATM transactions are private and do not involve any banking networks. I can only think of one company that charges a cash convenience fee to their customers.
