Want to destroy the morale of your honest and virtuous employees at the coffee shop? Have an open mic night. It's not poetry. It's not profound. It is horrid mind-shit, the likes of which might be a sampling of what runs through the mind of sterno-drinking street loonies.
I have stood witness to the most vile atrocities to decency, rhyme and reason and worse yet watched them go unpunished. This is a concept that should be banished from existence. Its where decent folks get conned into shakily performing bad poetry; forcing all their friends to lie to them and tell them how "deep" and "meaningful" it was. It is the reason the music got turned off. You cannot think, you cannot carry on conversation, you are being invaded by the poorly structured ideas of amateur closet poets in generally disastrous displays of their mentally monotone propensities.
