I took a taxi home tonight, and when I got home, the driver said to me: "318 yuan, just give me 300 to make it round, you can keep the 18 yuan." I said: "Master, let me give you 50, it's usually this price. You took a detour, didn't you?" The driver: "How did you know?" I: "My home WiFi has connected 6 times, and my grandma's WiFi has connected 3 times! My dog is wagging its tail on the balcony, it's almost exhausted!!!"
