Around here it is determined by who the driver is on the route. It seems that the women that work for FedEx don't like to lift heavy things so they roll them off the back of the truck. I don't remember any problems with UPS and very few with USPS which gets most of my business because I don't like the FedEx or UPS big trucks driving in my yard. USPS parks out front and walks the item in to my porch..
