Appropriate tag for an informal parcel pick up spot

Hello,

What is the correct to way to tag a spot where delivery companies are waiting for the customer to come pick up their parcels ? It's on a small island with no post services and it's an approximate position since it's not always the same companies and they are usually waiting somewhere on a small place.

There the node in question, and the tags I've used :
