What should you attach to the rental agreement once the wedding deposit transaction is completed?

The correct answer is to staple one receipt to the wedding rental contract. This practice is important because it creates a clear and accessible record of the transaction that connects the financial aspect of the rental to the specifics of the agreement. By attaching the receipt to the rental contract, both the customer and the store have concrete proof of the deposit payment. This measure helps in preventing any potential disputes about payment in the future, as it ensures that documentation is easily associated with the relevant contract.

The other choices do not provide the same level of clarity or organizational benefit. Keeping the receipt in the cash register drawer does not ensure that it is linked to the contract directly, which could lead to confusion later. Filing it with customer records does not create an immediate connection between the contract and the payment, reducing the efficiency of transaction tracking. Lastly, giving both receipts to the customer could result in the customer losing one or both receipts, which may lead to difficulties in confirming the payment later. Thus, attaching the receipt directly to the contract is the most effective and organized approach.
