You work as a barista, and there is a regular customer that always has a ice coffee.

One morning he enters at the normal time, and you already have his ice coffee made, standing at the counter, looking at him with a wide smile.

He walks up to you, and sees the coffee.

"This mine?" He asks with a pleased grin.

You nod and he takes the coffee out of your hand, your fingers touch for a second, you write your phone number on the receipt and hand it over to him. He looks at it and smirks.
