Not every household has an adult in it who neither works nor has no commitments during the day. I would suspect that most homes, actually, don't.
That's what I still find very baffling about our postal system.
I live in an apartment in a two building set up. You have the first set of doors from the street with a digicode (or just a button to press before 8pm) that gets you in a lobby with the mail box for the 2 buildings. right next to that you have the first building (with digicode) and after a small courtward my building, again with digicode. No where do you have a buzzer that lets you call for an apt and there will never be one; ever (buildings are way too old).
Normal course of action is postman gets there, buzz you, brings you your package if you're here or leave a note that he'll try again tomorrow if you're not, the package will only be available in two days at the post office.
Since he'll never be able to buzz (or even want to, poor postman if he has 20 packages and 187 floors to get up to!) and that it's absolutely useless to come by again, why in the ehell doesn't they just leave a note 'come pick it up, available today'?
I don't even know if they bother leaving the postoffice with the packages or not or if they do 'try again' (and do what, stand in the lobby for 10sec and leave?).
And that's the case for roughly 97% of the neighbourhood.
True, I've never went to the local postoffice and asked them if they had it from the first day, because there's a good chance it's not stored there yet.
I should ask next time.
They're only now starting to offer (only with very few merchants) the ability to just have it mailed to the postoffice.
They also built little hubs in train stations and big subway stations where they'll put your package, give you the code to the door and you just have to swing by and the way to work. It's not even manned so it's probably cheaper and more convenient for them too.
Another option sometimes is to have it delivered to your bakery or local café.
But all those are only for 'national' packages paid/sent by the post, it's not an option if I order from abroad.
