(I am talking to a customer about vaccines for dogs.)

Me: “The normal shots we give annually are distemper, parvo, rabies, and bordatella.”

Customer: “Okay. I wanted to be sure the distemper shot was part of it. My dog needs that.”

Me: “Okay. Would you like me to make an appointment for you?”

Customer: “Sure. Now, how long after the distemper shot will it take effect?”

Me: “What do you mean, take effect?”

Customer: “How long until my dog is nicer?”
