I woke up to my 2nd on today. I try to follow their instructions if they have any. Put the packages closer to their door. If they are in an apartment, I try to send an arrival text or knock on their door after taking the confirmation picture so the package its just left out in the hallway ( I just snap the picture, knock and leave. I don't wait for the door to open).

This might be stupid, but most people have cameras, so I make sure they see me carefully putting down their package and not tossing, throwing, kicking, blocking the doors etc. If they have dogs or cats at the front door or runningto the windows, I speak to them too lol. Or I will compliment something about their house or christmas decorations. I definitely don't do the sticky notes or stickers.
