Answer: The case does not fall within Consumer Protection law
Explanation:
The transaction doesnot fall within the consumer protection law. There is a binding Contract between Alex's Continental and Delores Bierlein. Alex's Agreed to provide Delores Bierlein with the Use of the Silver and return for Payment. Alex's Continental Inn has not breached this contract because they did not deny Delores Bierlein her Right to use Silver room.
The receipt clause that is stipulated by the Consumer protection law, it is there to protect the customer /Client int the case where the supplier denies receiving payments from the customer. Alex's Continental doesnot deny receiving $200 from Delores Bierlein, They acknowledge the deposit of $200 she Made. The issue of not receiving the receipt is not relevant in this case.
The Case here is not the issue of a supplier denying payment which that would fall with in the Consumer protection law, Alex's Continental Inn Acknowledges all Payments made ($200 deposit). The real Issue is the fact that Delores Bierlein wants her deposit back.
Venues for hire usually have a no refund Policy, meaning a No refund policy on deposits is a common policy in the business of venue rentals simply because when you book a venue the reserve the the venue for you even if another person wants to book they are legally obliged to hold the venue for you.
Assuming Delores Bierlein was aware of the No refund policy, Alex's Continental did not deny her the use of the Silver, they are well within their right to refuse paying back refund.
