The delivery man called me a minute before to inform him which was my house. He simply opened the door and left the package at the entrance of the building. I live in a block of flats where we are all family.

Perfect DNA material.

The driver's word holds no value to verify shipments.

I think DNA could works

It will.

but the same company has to leave me another package in a couple of days, and I'm afraid it's the same delivery person.
Should i do Lit and keep this away?

Use another method for the forthcoming delivery.

If it's the same delivery guy so what? It's his job to deliver the package anyways...

He may well be questioned as to why he failed to deliver 2 packages In such close timing at the same address - which will affect him on a personal level.

You must avoid a personal Impact when social engineering.
