nah I prefer them to leave. before covid the post here was notorious for not knocking, and dropping a card meaning you had to go to a post office and collect it in person, but only during business hours, you had to line up behind all the old people who paid bills at the post office, finally get your chance and if you are lucky they would find your parcel, but usually either way they would make out like you are being the biggest inconvenience in the world.

these days they drop and scan, sometimes knock, sometimes not, but it doesn't matter. havnt had a theft ever
