Coffee House Fred

If you take Soens' suggestion, you might hear someone order a venti espresso half-caff with chinchilla milk froth and a sprinkle of cinnamon and nutmeg with a faint dusting of ground vanilla on the rim of the cup. When the barista answers back, "Bapu, you do this all the time," then you might begin to realize the full impact of your actions. By posting in the Coffee House while sipping coffee in a Coffee House, you have unwittingly opened a wormhole into the Coffee House. (No, not the one you're sitting in.)
 
That may not seem like such a bad thing at first. I mean, there are some fine musicians in here. Think about it. Can you imagine what your world would be like if Coffee House denizens found their way into your world? 
 
That thought may prevent you from ever visiting another coffee shop. Some consequences are too horrifying to be worth the risk.
