Postpeople and Porches

I am just wondering if I am being unreasonable? For years we have had a porch on the front of our house. All panels and the door are full glass so no option for a letterbox in the porch or door. However if you open the door which is never locked the letter box into the house is 2/3 feet in front of you. 99.9% of our postal deliveries are successfully made with the post being put through the letterbox. Very occasionally a new or temporary post person delivers our post but rather than putting the post through the letterbox they just throw it in the porch for all to see. We had such an incidence today so Margaret was on the phone straight away. Usually when this happens we get an apology with a promise to talk to the person concerned and problem usually solved. However today we were told that the post office cannot force an employee to enter a porch if they, as an individual, feel they are trespassing. Perhaps they feel that opening the door without setting foot in the porch is not trespassing? The man at the post office did reassure us that post should never be just thrown in a porch and if the post person is unsure they should return the post to the office! Has common sense completely gone out the window? Was the person just being lazy? Oh and BTW they left the garden gate open on the way out but I won't go there!!!
