It seems like fedex in our area gives you about 3 nanoseconds to get to the door for a signature required package. When you don't make it, there are zero chances for redelivery same day and it's a drive across town for the item. As I usually plan to have myself or wife home when delivery is expected, when it is missed I end up driving to get it rather than plan out another whole day. Annoying.
Never this issue with UPS.
FedEx is the king of Ding Dong Dash game... I know I'll be spending tomorrow all day with the door open and in fear of even running to the bathroom for 20 seconds. Oh the joy...
