Do (m)any companies attempt to drive sales by describing a product as "adequate"?

If your child sits a school test and the teacher describes the result as "adequate" would you be content?

In the workplace why wouldn't one want to always aim to do "good" work (which is very definitely one step above "adequate"). That doesn't mean amazing, outstanding or exceptional. It also doesn't imply pressure.

Why would anyone approach a keyboard if they weren't attempt to do something good?

Put another way, who gets out of bed aiming to be adequate? It's not like it even sounds like an aim, it sounds like it happens when you're not paying attention.
