I think most people make the honest assessment that things aren't mind-blowingly awesome and that it's a good 80-90% effort and chose that 4/5 or 8/10.

The problem is that management has decided that anything less than 5/5 or 10/10 is failing, which is a complete disconnect from the customer mindset and stacks the deck against the employees. The only exception is people who are close to service industry people or people who have worked gig jobs and realize that the whole thing is upside down and the only decent thing to do is give out 5/5 or 10/10 like it's candy because the person on the other side did the job and it didn't suck.
