Planet Earth is blue and there's nothing I can do

A man ordered one of my company's products and selected Ground shipping. After tracking his package, he complained that Ground shipping is "unacceptable."

I was not aware that UPS ever took 1 week for a package delivery.

He works at Johns Hopkins.

US Postal Service only takes 3 days from west coast to east coast for a simple letter. This seems quite unreasonable and from your web site I was not aware of this extended time frame for receipt of a simple package.

How do you look at the shipping methods and deduce that Ground shipping takes three days or less? It's fuckin' listed below 3 DAY shipping!
