Call center agent: I’m sorry, but for international calls, you’ll have to contact your zero operator for information.
Customer: You can’t help me?
Call center agent: No, I only provide listings in North America.
Customer: What?
Call center agent: I am a 4−1−1 operator. You need the zero operator.
Customer: What’s the difference?
Call center agent, sighing: The zero operator can help you. I cannot.
Customer: So you’re useless?
Call center agent: In this case, I am completely useless to you, yes.
Customer, to friend in same room: Hahahaha! She admitted she was useless!
Call center agent: [Slooow exhale.]
