Exactly. The only situation I could see this being remotely socially acceptable here in the UK is if you have the same postman or delivery driver every day, and you somehow decide at Christmas to give them a Christmas card with a little something in it. Even then that's a bit weird.
At the minute my delivery drivers seem to have no concept of social distancing so they're lucky if I don't shout at them / report them.
Seriously, half the time they knock and literally just wait 1 foot away from my door. Even when I've given explicit instructions to leave the package on the door.
I had covid 3 weeks ago and one of the delivery drivers made me go to my front door to take a photo. Even happens with items with no significant value, like food deliveries, even when I've selected the option on their website, to leave the delivery on the doorstep. They just knock and wait...
I get it, they need proof of delivery, but they need to be able to respect social distancing too. I had a delivery driver do this 3 weeks back when I actually had covid and was essentially incapacitated. I told him this through the window and yet he still asked me to come outside and stand at the door so he could take a photo.
