A mini office vacation. Feeling tired? Have that after-lunch-coma? Take a porcelain cruise! The act of locking oneself in a bathroom stall for 20-30 minutes in order to take a quick nap.
After that heavy lunch, I'm exhausted. Think I'll stop off for a porcelain cruise to relax for a while. Hope no one else comes to stink up my little vacation!
