They probably err on the side of caution on shipping time. I used to order massive ship loads of steel from Japan (only place at the time to regularly ship cold rolled extra deep drawing steel) , we’d telex (gawd, I’m old) the ship once a week for an update, they’d send back lat & long, we’d look it up and track progress, I always remember a telex after a big storm in the Pacific, the ship was 450 miles behind where it had been the previous week, the storm forced it backwards halfway across the Pacific.
We couldn’t call the steel works, they shipped free on board, so once on the ship it was our product. If you did need to call, it was fun, a secretary answers phone in Japanese, I’d then say “Hello, I’d like to speak to Mr Kakagawa please” and they would instantly hang up without saying a word in any language.
Our production team (fire extinguishers ) were not happy to be told the ship was running 2 weeks late.
In life, it's not who you know that's important, it's how your wife found out.
