My company recently entered the laptop battery market, which tripled the size and weight of our daily shipments. The UPS guy is none too thrilled.
If he could hear my thoughts:
"HELLO!!! You are a UPS guy! Moving heavy objects is part of your job! Also, our warehouse is on the ground floor right next to this office park's UPS drop box! Your truck is 25 feet away and you have a cart that expands! Quit yer moaning!"
