Could be because they can make life easier for you if they know, or just fun

I've been driving for Amazon for a few weeks now and here's what I got

• We only see delivery instructions once we park by your building, so telling us which streets/gates to use on the way is useless.

• Also, we lose access to them once we finish the delivery (basically right after we leave the package on your doorstep) so if you for some inexplicable reason have an INTERNALLY locked gate, have the code/button somewhere clearly visible because otherwise we can get stuck (like i was for a bit yesterday)

• All that said, you can really make them useful by being clear and specific about things. If the keypad to open the gate is hidden behind some shrubbery, let us know. If it's a confusingly laid out apartment complex, tell us which way to turn as we exit the elevator because you could be the only person with delivery on that floor and we don't want to waste time walking to the wrong end of the building
