Why is dealing with government documents and purchases in Thailand so complicated?

Holy crap..... bought new Mitsubishi truck. Get called in as government rejected 1st passport photocopy, so we take new one in. Called again to collect new book, name spelt incorrectly. Sent back for change, comes back with passport number missing digits. Sent back again. Finally....or so we thought.... everything ok. Mitsubishi just called, they've put my date of birth as 20/01/2020, or as I would call it..... the date my passport was issued!!. Oh and apparently I've changed nationality to American from British. If only that part was written clearly on the passport page! At least Mitsubishi have taken pity on me and now deliver the book to me each time it's returned, I think they like my coffee. Rant over, enjoy your weekend
