I remember once in India I took an Uber, and the driver asked for a good rating. He had been nice and I wanted to give him a 5-star anyways. But as I took out my phone, he helpfully grabbed the phone from my hands and proceeded to enter the 5 stars himself: "click this, and then this, and this ...". Just made me chuckle. He knew what needed to be done, and proceeded to do it.
