I had to cover the phones while the switchboard went on break. This call came in:
"Good afternoon and thank you for calling XYZ Corp"
"You just called me."
"Uh, no, you just called here."
"No, you called me. It's on my Caller ID"
"O.K., but it wasn't me."
"Are you sure? I called you back and you answered."
"Yes, I'm pretty sure I didn't call you. You're calling a switchboard."
"So, you didn't call me?"
"Do you know who did?"
"Sorry, can't help you. It might have been a misdialed number."
"Can you check for me?"
"No not really."
"O.K." and he hung up.
Now I remember why I work in the back offices.
