Mail service in different countries
I think Japan has the best postal service. I almost lost my parcel in Singapore when the post lady did not go up to my unit and left the non-delivery slip on the parcel itself. Because there was no notification in my mailbox nor doorstep, I continued to wait for 2 days at home until I thought it was strange and went online to check. Luckily I managed to check on the last day that I can collect my parcel before it was returned to sender. Fortunately the post lady at my parent's home was much better and even recognised a wrong address and delivered it correctly to us!
