My favorite of the UPS tricks is the honk or knock and run. At my ex in-laws house they used to honk the horn of the truck, then put the package in her garage. In my case, IF I'm home, they knock on the door, then run before you even have a chance to answer the door and sign for it. I think it's crazy and if more people 'sock it to em' when packages are missing perhaps they will change their procedures.
