In a restaurant, a customer was astounded by how quickly the waiter responded to his needs. As soon as he though of it, the water was there, the menu, or whatever else he wanted was instantly in his hand.
The customer called the waiter over and said to him, "You're pretty observant! I've never seen anyone watch me so carefully."
"Thank you." said the waiter.
"Well, cut it out. You're making me paranoid."
