Re:If you can't trust the UPS driver ...
Our USPS guy and the UPS driver are welcomed in our home often. If the weather is bad, a refill of their thermos with hot coffee is appreciated by both. Xmas treats have gone to both of them already this season...Plus the UPS guy now has a big sample of our smoked Bacon for his lunch sandwiches.
Both of these guys have gone the extra mile, literally to give us excellent service, and we appreciate them very much.
We keep a Coleman cooler near the back deck with a UPS sign on it, so the driver can put any packages in a weather-proof container if we aren't home.
