Every day around 3:30pm we go around and deliver the mail and packages we've received during the day. If there's anything for you, we'll leave it on your desk unless it's something big and heavy. In that case you'll have to come and pick it up from reception.
Note: You don't really have to wait for the 3:30 delivery. If you are impatient and you know you have a packaged delivered, you can go straight to reception and pick it up.
