UPS isn't much better. I won one argument with UPS. I took a golf club to the UPS store and had them package it and mail it. It arrived bent. They denied the claim saying it was not properly packaged. I told them your store packaged and mailed it. After a silence they agreed to pay for it. That was years ago when email and endless phone menus were not the norm.
Just a heads-up: that only works with UPS Stores that are owned by UPS. Many of the stores (perhaps the majority) are franchised. UPS will deny responsibility if they don't own the store.
