For Him, The Cup Is Always Half-Empty

(While I am working on cash, a customer comes into the coffee shop, outraged.)

Me: “Hi! Welcome to [Coffee Shop]. How may I help you?”

Customer: “I was in the pathetic drive-thru, and they only filled my cup halfway! See?” *shoves a cup in my face*

Me: “I am so sorry. Let me get you a new one right away. What drink was it?”

Customer: “A double-double.” *hands me his old cup aggressively while cussing continuously* “Give me one of those free drink coupons, as well.”

Me: “Of course.”

(He’s literally shaking as I hand him his new cup and coupon; he snatches them from my hand and leaves.)

Manager: “Don’t worry; he did that yesterday, too.”
