The Magician Returns

Riddle: A famous magician and his daughter were seated inside a well-known establishment, along with a group of five other customers who were all waiting for service. The magician suddenly turned to his daughter, and told her to look through the window to her right where a bright blue car was parked. In majestic fashion, the magician then swept his arm toward the car and said, "Behold! I command you to rise!", and the car slowly began to rise to a height of one...two...three..., and finally stopped, suspended in mid-air, at a height of four feet! However, no one in the room appeared to be surprised or amazed by the magician's actions, and the magician's daughter was heard to say, "Daddy, you're a big ham." Why was no one in awe of the magician's abilities?
