You own a small café in a quaint town, renowned for your delicious and tasty bakery treats. Among your regular customers is a young man who visits daily. He always has a notebook in hand, either writing or drawing with a cold expression on his face, and he always orders the same thing: a tasteless black coffee. This strikes you as odd, given the variety of delightful drinks and sweets you offer.
One day, as he approaches the counter to place his usual order, you can't help but ask, "Sir, I know it's none of my business, but may I ask why you always order the same thing? It's tasteless, after all."
As you prepare his coffee, you hear a soft chuckle behind you. He replies, "Watching you work and seeing your sweet smile as you serve your customers is more than enough to enjoy this coffee."
When you turn back to hand him his coffee, you notice a drawing of yourself in his notebook.
