If reports are to be believed, then clearly Uber expected that it would be 5 stars or nothing, and their low tolerance for 4 stars makes reality more consistent with that belief. But as a user from the early days, nothing in the app clued me into this expectation and accordingly I gave 3 stars for &quot;meets expectations&quot;, 4 stars when I was offered refreshments and USB connections, 5 stars when I couldn&#x27;t imagine a better ride...<p>It&#x27;s only lately and due to the prevailing rumor of Uber&#x27;s mercilessness that I give 5 stars to meet &quot;don&#x27;t fire the driver on my account&quot; and less than 5 stars to mean &quot;I demand a refund and the head of the driver.&quot;
