Being A Good Sport (Drink)

(The plasma donation center where I work has been experiencing a saline shortage and as a result has a very strict rule about donors drinking a sports drink before leaving. I’m manning the front desk when I see a man leaving without even touching his drink. I’m a female in my late 20s.)

Me: “Sir, you have to finish that before you leave.”

Manager: “Nah, I’m fine.”

Me: “Sir, it’s the policy.”

Manager: *getting louder and advancing slightly* “What are you going to do if I don’t? Spank me?”

Me: *in my most perfect deadpan* “Not for free, sir.”

(He burst out laughing and finished his drink without complaint.)
