Postman just tried my (locked) front door handle when an item wouldn't fit in the letterbox. He hadn't even knocked. I could see this happening from the inside and opened the door - I asked him if he was trying to open my door and he said he was only going to leave the item in the inside of the door. I said that I didn't think he should be attempting to open people's doors and he got a bit shirty.
Is this a thing?! I don't know him and he is not a regular postie - in fact, the postmen in this area change frequently. Just made me feel uncomfortable - does your postman/woman do this?
