, I am sure poor philamb did not realize you are a honored member of the USPS force.
truffle schmuffle, head out and find yourself some new world chantys that reek of apricots. 
You are so correct and I do have a source for Black Perigords here in the good ole US...
I just cannot imagine the terrible experience Phil must have endured to reflect that opinion....
I would love to give him a tour of a USPS facility and elighten him...they even have
welding hood viewing galleries surrounding the work area so inspectors can do voyouristic
anonymous things at all times...or any time ....no one knows but the inspectors. We are
heavily watched for sure....Misrouting...happens....stealing usually not..
My comments were indeed generalized, for that I apologize. I have had absolutely
atrocious experiences with the post offices in NYC and Chicago. Never, ever a good experience, not a single time. The best is that I get the stink eye (as opposed to "hello") and the worst was the time I was yelled at (yes, for real) for not filling out a form correctly. And yep, in both NYC and Chicago I've been delivered letters that had been opened (like you would a normal envelope, not like something that would happen by accident in a sorting machine) and re-sealed with tape. Typically greeting cards.
Of course, La Poste in France isn't much better, but just like the US it depends on the branch. My local is very nice, but the one time I tried to send a package (of beer) to the US from a branch in Paris, the lady at the counter insulted me several times and joked to her coworkers about my grammatical mistakes.
