Yikes Andy......Relax.....All will be well. If you miss a delivery, they will make 3 attempts before sending it back. If you call to have it held at the hub, they will hold it for 5 business days before sending it back. If you trust your building mngr. then go for it. I have heard of drivers not giving the package to someone other than the addressee but perhaps if you leave a note with the bldg. mngr. the driver will release it.
As for listing your physician's name, I always put my childhood family doctor's name and his old phone #. He's dead now so I have'nt had any trouble.

Hope this helps....
