Me: “Hello, *** Customer Support, how can I help you?”

Customer: “Hi, I have a problem with my bill.”

Me: “Let’s have a look at it, can you give me your customer number please?”

Customer: “Sure, it’s…”

(While he gives me the number, the fire alarm goes off.)

Customer: “What is this noise?”

Me: “It’s the fire alarm, Sir. I’m afraid I have to call you back later.”

Customer: “Oh, I see. Well, can we go through my bill now?”

Me: “Sir, I’m afraid I can’t do this right now. The fire alarm is on and that means I have to leave the building.”

Customer: “Yeah, sure. So, my bill–”

Me: “Sir, I will gladly check your bill once the alarm is out and the building is safe, but now, I really need to hang up and go outside.”

Customer: “But my bill…”

Me: “Sir, I’m afraid my pants are on fire, so I’d appreciate it if you could agree that I’ll call you back later.”

Customer: “Oh! Okay then, call me in an hour and I hope your pants are fine.”

Me: “Thanks. Bye.”

(My pants of course were not on fire, but I don’t think anything else would have shut him up.)
