Waste on the construction site - What is tolerable?

You can exaggerate everything if you have no other problems.

You can also let everything happen to you.....

There is usually the healthy middle ground..

I'll guess... you are a non-smoker :-p

There is usually the healthy middle ground..

Exactly.

You can also put up with everything.....

Have you ever talked to a construction worker and pointed it out to him?

Go ahead and have fun with it^^

Depends on the relationship.

If you meet the craftsman on equal terms, talk to him, show interest in his work, have a cup of coffee, then you can also say, "I don't like this. Please change it."
That works.

As a client who only complains, you won't achieve anything. Everyone shuts down as soon as you enter the construction site.
