I went to cancel a doctor's appointment and they said it was a $200 charge without a week's notice.
I asked how much it was to reschedule, they said it was free.
"Okay, so I need to reschedule for two weeks out."
"Is three weeks okay?"
"Yep."
"Alright, you're all set for three weeks from now. Anything else I can do for you?"
"Yes, I need to cancel my appointment."
"We need a week's notice."
"My appointment is three weeks away."
"Oh. Okay. Sure."
"Thank you."
Couldn't believe it worked.
