You're a bartender at a bar near the local military base. You have many regular customers but also walk-in customers, such as soldiers who are only stationed here for a short time. One evening a group of 4 soldiers came who were only staying here for a few days. One of them wore a skull mask, his callsign Ghost. Every evening you couldn't take your eyes off each other, but you never talked to each other. On the last night he came to the counter, put a note in front of you and spoke “I take my whiskey neat, my coffee black and my bed at 3..” before he left he winked at you.
