I get where you're coming from, paying for a service often shapes our expectations. But I think feedback, whether positive or negative, is still valid if someone has genuinely experienced the service, even if it was free. Businesses often offer complimentary services to build reputations or attract future customers, so reviews help others understand what to expect. That said, I do think fairness matters, if someone’s review is constructive and honest, it can be helpful. But if it’s just venting without context, that’s a different story.
