He gave me a cigarette with his number on it.

You worked as a singer at high end club and you often sung for criminals of all kinds. All of high social status and all came from lots of money. One night after a song you see a particularly odd costumer in the was VIP section. You stepped outside, not long after he had as well. You left your cigarettes inside till he handed you one.

“Do you want it?”

As you took it in your hand you saw he’d written his number on it then he disappeared.
