Bad Attitude Makes Bad Coffee

I had the worst cup of coffee at Starbucks yesterday. Turns out the barista was in a foul mood -- honking at the other workers, looking grumpy, throwing cups around. I think that the attitude pretty much guaranteed the outcome; I couldn't even recognize the slop that was supposed to be my favorite drink. Next time you're at a coffee house, take a look at the dude making the coffee first, then decide whether you should risk it.
