Do people shop the same way they review books?

Maybe I've been in retail for too long, but I think there's a link between the way people shop and the way they review books. I've recently been reading book reviews of authors who are self-published (like I plan to be). I wanted to know what I should expect when the time comes to release my book into the world. Every review I've read, the good, the bad, and the ugly, have all been like customers I've had. There's the customers that don't want to be bothered, they probably won't review at all. The customers who look at the item from every angle: the reviewers who pick the book apart. The customer who happily asks for suggestions: the reviewer who reads and comments on other people's reviews. I think the customers/reviewers who are open to suggestions are my favorites and that's probably the category I fall under when I shop or review. I'm always looking for something new to read so if you have any suggestions just leave a comment. There's the customer who knows what they want and often leave happy: the reviewer who reads the same types of books or authors all the time. Then there's my least favorite, the customer who finds a blemish and wants something free. This type of customer is equal to a review who isn't reviewing the actual book, but instead something like the font size or formatting. They don't actually review the book, but they do give it a negative amount of stars. I hate seeing that type of review for anyone's book, but I know I'm bound to get a few of those myself. Despite that, I'm still looking forward to starting my journey and living my dreams.
