Pretty well known restaurant in Chicago:
Valet "You have a nice car sir, but something is wrong with your car. It just doesn't accelerate well"
Me "What do you mean? Why were you trying to push the car hard?"
Valet "We weren't"
I get in and turn off valet mode on JB4
Me "It accelerates fine kiddo (probably older than me but I was annoyed), don't abuse client cars"
I could see his jaw wide open in my rear view mirror as I took off.
