After I watched a movie alone in the theatre. I craved some cold iced coffee. I went to a nearby stall and then asked for the same. When the vendor gave it to me he didn't really look up and did his work. I had already done the payment online so I saw him the screen just for his reassurance. He just smiled at me and said that he already knew, like showing the screen wasn't needed. I mean it's not something major but yea his smile felt safe.
