I friggin love Starbucks.  I don't have the energy right now to write this whole article, so here's some repurposed content:

From the Salem, Oregon Statesman Journal: A man walked into Salem Starbucks and sat down without buying anything. When asked to leave, he threw ice on an employee. The man then took out a hammer and slammed it against a table, damaging it, and yelled profanities at employees and customers before leaving. A familiar episode? Can you top it?
