“Let’s party!” is still echoing in your head as you leave your Principles of Purchasing class.

The decision to have a year-end party was right up their alley, and class had ended with a chanting session of “Let’s party.” It sounded like a wrestling match to you. Fortunately, your professor had left the room early to let you discuss with the class the idea of some kind of year-end get-together.
