Although they are in general quite bad, in my local area they are surprisingly good - for one reason - that specific delivery driver has significant local knowledge.
Getting the right staff in the right place sometimes makes a big difference.
I think it's that they give the delivery drivers a stupidly short amount of time to make deliveries, so it's up to each driver how they handle it.
Some take their time and work slower, some leave them buy your front door and don't ring the bell, some dump them over the fence, and some just mark them as delivered and drive home with the parcels.
I would pay him, but I never seen him. When he finds the house at all he puts the parcel at the baby buggy of my neighbor or directly in the paper collection bin.
Ah yes. There is that. Much fluctuation. OTOH you can teach the ones who make it. If 5€ are worth their while is another matter. But if the whole house with all people teaches them the same way, poor delivery minion learns: good house!
This may sound sarcastic, but it is how it is. I don't envy the subsubcontracted
delivery people, and I fume at the thougt of privatization, outsourcing to the lowest bidder, while their websites proudly present meaningless labels praising customer satisfaction, trust, reliability, whatever, while their hotlines are useless. But again, that's just how it is. I can't influence that shit. Except by 'tipping' the scale of the stressed, overworked, and time pressured person towards that 5€ dangling before his eyes, if package is delivered to my door.
