Havingworked for UPS for almost 10 years, I can tell you truthfully by firsthand experience that when the employees themselves call UPS "United Package Smashers" they speak accurately. Management gives lip service to treating every package as a "guest of honor" but they're hypocritical liars because their first and foremost priority is their profit margin and cramming packages into trucks as fast as humanly possible.
Here's a good rule of thumb for deciding whether or not to use UPS. If it's a letter or something non-breakable, and you need it to arrive quickly somewhere, then by all means use UPS. They're the fastest.
If the contents are fragile or precious to you or the receiver, then go with Fed Ex of the U.S. post office. Statistically those two companies pay out far less money in damages to their customers than UPS has to because they actually do care more about their customer's goods than their bottom line.
