A Tale of Chocolate and Coworker Conflict

So there was this girl at the coffee shop who always seemed to be in a hurry. She'd give me orders without a smile and rush off before I could even finish making her drink... One day, she came in and dropped an extra large double-shot-on-top mocha order with an attitude that made my blood boil. But then something odd happened, I decided to make it for her the same way I'd do for anyone else. As I prepared her drink, this thought crossed my mind: 'Why am I letting her ruin my day?' So, as a little prank, I slipped in some extra chocolate syrup and put double sprinkles on top... She seemed surprised when she tasted it, but didn't say anything, just grabbed her coffee and left. I felt oddly triumphant that moment, like I won some kind of silent battle...
