But this is the same postal service that returned mail to Australia because the sender forgot the "care of" name, on an otherwise perfectly addressed letter. ie: yokine, c/-flatmate, xstr.... vs yokine, xstr...

Though they had been delivering mail in the first format for about six months. One slip up and it was back by seamail. we though it was lost in the mail, but it showed up at the senders home after about 3 months. Oh an apartment number on the mail box would be such an unworkable system
