I used to work for FED-EX. we deal with so many things and are in such a hurry we don't pay attention to things like that. Like i always figured. If you are expecting a package then you need to either be there or have your dogs put away. we worked 10-12 hour days with no brakes and running every stop. They can't leave it at the gate and they don't want to have to come back tomorrow, so thats why they just leave it.
