For that reason I think it’s worth drawing a distinction between rating service by very small businesses (taxi drivers, family-run guesthouses, etc.) vs. a mass/retail product. Rating the former tends to be 1) personal, 2) having much influence over individual’s livelihood, and 3) much more dependent on my preexisting expectations. If there was something I didn’t like, I try to not give any rating instead of rating poorly unless there was an exceptional issue. Rating a product, especially by a bigger company, 1) does not necessarily criticise the company itself (I can still admire it while objectively having bad experience with a unit) and 2) has much less influence over company’s overall success (my review is probably a drop in the ocean), and 3) I tend to think of it as more objective than rating a service (compared to a service provided by a human, when evaluating a physical product there’re absurdly fewer variables and you’d be better informed about what you’re supposed to expect based on tech specs).
