Everything is ASAP. They are super excited about everything. And nothing you do is wrong, it just could be improved or they like it but don't love it.
You don't know if something is important, basically.
Just like Louis CK said, "if you used 'amazing' on chicken nuggets, what are you going to say when your first child is born?". But in reverse.
Personally, I'd rather work with someone who would tell me my work is terrible if it is.
In Germany, you can't even legally say somebody did a bad job at your company in a recommendation letter. Companies created a whole subtext to workaround that, it's crazy.
Some things are just bad. You should be able to say it is. Not by saying it could be better. Not by using euphemism. It's just something that needs to go to the trash.
In fact, I don't trust people who can't receive this information, even if not packaged with tact (which you should attempt to, but life happens). If you can't handle people not being perfectly polite every time, I can't help but feel I won't be able to count on you when things get hard.
That must be the French in me talking.
