Even though it would probably be OK, I could not continue working knowing that I had a new addition sitting at the FedEx office. If it were me, I would take an early lunch break, pick up the package and get in a quarantine rack. Then go back to work.

If you know the package is coming before 10:30 am and you track the package, you should be able to schedule your lunch time or time-off for pickup.

I have all my deliveries come to the FedEx/Kinkos store in my office building. They deliver straight from the airport and the FedEx shop is air conditioned. That way, the box is not sitting in a hot truck as it makes deliveries on the way to my house.
