A Valentine’s For Over-21s Only

I am seventeen, working as a grocery store cashier. As I am under 21, I have to have an over-21 coworker ring up alcohol. My manager comes to scan a customer’s champagne. He is also purchasing flowers, a “Happy Anniversary” card, chocolates, and a box of condoms. As the manager finishes scanning, he says: 

Manager: “You have a nice day, sir.”

Customer: “I sure will!”
