Does the bus count?
If so, as a seemingly normal guy was getting off the bus he said to the driver, "Thank you, bus driver."
The bus driver didn't reply, just looked forward. The man repeated, "Thank you, bus driver." No reply.
The man starts walking out of the bus, voice getting louder, "I said thank you, bus driver." The bus driver is staring forward. The man is now screaming, over and over, "I said thank you, bus driver" as he leaves the bus, walks across the street (in front of the bus), and as he's standing on the corner continually turning to face the bus as it drove away. Many people on the crowded street were stopping and staring at the guy.
Many blocks later, when I got off, I said, "Thank you, bus driver." He just subtly nodded his head.
