Part of the marketing strategy that has made Starbucks an international juggernaut is the calculatedly homey atmosphere of its stores (if your home had industrial furniture and weird murals of mermaids who shill coffee). Unfortunately, that seems to lead some folks to treat their neighborhood Starbucks as mere extensions of their homes instead of, y'know, public eating places.
Yesterday morning, as Amy and I breakfasted in one of several dozen nearby Starbucks, I saw a gentleman in his 20's at a nearby table working on a Vaio laptop. He had his earpods plugged into the laptop, his flip-flops off, his bare feet up on the seat opposite him, and his bare toes curled around the chair rungs. No regard for whoever would have to sit in that chair after his sweaty feet had their way with it.
I'm sure the next step (if it hasn't already happened) is folks showing up in their bathrobes and boxers for their hourly shot of caffeine.
