A man brings his ailing Chihuahua to the veterinary clinic. Without delay, they are escorted to a consultation room.
Shortly thereafter, a Labrador enters, investigates the Chihuahua for about ten minutes, and then exits. Next, a cat appears, gazes at the Chihuahua for another ten minutes, and leaves. Finally, the veterinarian enters, gives a prescription, and presents a bill totaling $250.
“This can’t be right,” the man exclaims. “We’ve only been here for 20 minutes!”
“There’s no error,” the vet replies. “That’s $100 for the lab test, $100 for the cat scan, and $50 for the medication.”
