Earlier quoted context omitted.
Minus the necessity of the wreath, I assume construction managers in the US are equally willing to accept free drinks and an extra $100/per bathroom. Does this not work in the US because it can't be a reasonable default in those types of situations?
It's not a reasonable default because every visitor to your house would make a comment requiring you to justify having "fringe" bathroom habits. Edit: Not every, of course. And the number would vary by region of the US. Excuse the universal quantifier :)
Edit: After reading the other comments, it is apparent that this is probably a good idea for primary users too. Makes sure the job is done right.
