The current culture of giving, sometimes being directly requested to, and the inference that the only option is to give 10/10 is not useful.
If vendors only want 10/10 then there is no difference between qualities of products.
Yeah, there’s a correlation between price and rating, and 10/10 for £50 bud is not the same as 10/10 for £100 but it’s not really useful as a metric at this point and makes it difficult to make informed decisions.
This is further exacerbated by vendors requesting 10/10, and the fact that if you don’t give that you might be barred from ordering from them.
So what’s the fix? More granular rating system maybe, where product is divorced from comms/vendor/p&p etc.
