See it doesn’t matter how keys are generated as they’re sold on an individual basis. Thus You can keep track of the exakt Credit card transaction that was used to buy each key. If You don’t save this information linked to each other then it’s your fault as the store manager.
Don’t try to shift a problem of sales management to the customer. It doesn’t solve your problem but makes you looking yuck.
Acting pathetic doesn’t solve your problems.
