Tough Guy no. 1265 remarked:
DPD deliveries I get are almost always right at the beginning of the
window, so perhaps they've been waiting round the corner for the clock
to tick on.

But if you are in, there is no reason for them to wait.

Agreed, but that depends a bit on whether there's somewhere they can
easily park outside the house while waiting. At my current house there
is, but my last one there wasn't.

Why not pull into your driveway?

Many houses don't have them.
