[mothered]

ok thanks mothered.

You're welcome.

I only have one last question before proceeding.
when the courier comes home, do I have to put a completely different signature or should I use a name and surname very similar to mine?

Use a completely different signature, that does not correspond with your name.

Be sure It's somewhat legible (readable) so when they cross-check the name, It will not be associated to yours, hence It wasn't "you" who signed the delivery.
