Me: “Sir, I’m afraid your SIM card has been destroyed due to entering your PUK code too many times. You will have to get a new one.”

Customer: “Ok, thanks.”

(Some moments pass and he hasn’t hung up. I put the phone on mute.)

Customer: “Stupid b**ch!” *miscellaneous other insults*

*mute off*

Me: “Uh, sir, you might want to disconnect the line, I’m still here.”

Customer: “OH F***!” *click*
