I haven’t had a delivery person knock in quite a long time. Package deliveries haven’t knocked in close to 20 years. I’ve even noticed DoorDash drivers don’t even knock anymore, they awkwardly stand in front of the porch and try texting. I now open the door as they are walking up to the porch to avoid that. I don’t know if it’s a policy or some kind of shared anxiety, but I find it really weird.
I had one food delivery driver call me while standing in the middle of the street. Seemed like he was afraid to approach and knock or ring. So strange.
Some people get really weird if you approach their house in a way they don't like. I imagine if that happens a few times to you as a delivery driver, you might be more cautious.
I know people like this, but would assume if they ordered a delivery that the person would be expected and not a cause of alarm. If someone can’t handle a person coming to their door, they shouldn’t be allowed to use delivery services.
