Theft? What?

I am working late at a veterinary hospital and a note was left for the doctor. The phone rings, and I answer.

Me: “[Veterinary Hospital], my name is [My Name]. How can I help you?”

Owner: *Politely* “Hi there. I left a note for the doctor this afternoon and I haven’t heard back yet. My pet’s name is [Pet] and my last name is [Owner’s Last Name]. I was wondering if we could fill antibiotics for my pet?”

Me: “Okay, let me look that up for you!” *Typing* “Oh, I see the doctor won’t be in until tomorrow. Sorry about that. My coworker should have let you know! She’ll get back to you tomorrow, but I’ll let you know that standardly the doctor does require a recheck exam prior to filling antibiotics, especially since it’s been a couple months since we’ve seen the pet!”

Owner: *Silence*

Me: *Pauses* “Ma’am, did I lose you?”

Owner: *Suddenly angry* “No, I heard you, but that’s theft.”

Me: *Shocked* “What?”

Owner: “That’s theft to demand a recheck!”

Me: “Ma’am, I was letting you know so you have a realistic expectation of tomorrow’s call with the doctor and to see if you wanted to make the appointment.”

Owner: “That’s theft!”

Me: *Sternly, getting back my senses* “No, it is not.”

Owner: “Yes, it is!”

Me: “Ma’am, if you continue yelling at me, I will have to hang up.”

Owner: *Yelling* “I’m not yelling!”

Me: “Yes. You are.”

Owner: “I’ll talk to the doctor tomorrow!” *Hangs up*
