Wierd. UPS Delivers to my door only when I am at work. Then, if I don't want to/can't take time off, they tell me I must pick it up between 7 and 9 pm, as those are the only acceptable times, unless I call and arrange a pickup at the office instead of a delivery. If I am really lucky, when I call and arrange for a pickup, they will actually keep it in the office, and won't send it out on the next day's truck. After 3 attempts at this, they return it to sender.

I guess you don't live somewhere interesting and/or don't leave the house.

UPS delivers to my door too - but they literally drop it there, ring the doorbell and leave.

If it's raining, the package gets soaked.

If the neighborhood kids are particularly rowdy, my package is gone when I get home.

Dropping it off at a specific location and requiring me to show up and prove my identity before I can take it home fixes these issues, among others.
