From Noah Sanders at Sprudge.com:
I have a confession to make. Today I work in the corporate world, but in years past I was a barista, and during that time—when pushed to the brink—I engaged in the dark art of “decaffing” customers.
Yes, I have gone against the code of customer service to expressly, and covertly, betray the order of a valued guest, replacing what they believed to be a luxurious shot of fine, highly caffeinated espresso with a trick shot of caffeine-less decaf. I have knowingly, and with vengeance in mind, deprived a handful of customers their daily, or twice-daily, dose of coffee-produced energy.
