I currently work in a call center. Today we were really slow, and I was enjoying the long break in between calls. All of a sudden, a manager dials my extension and says "Hey John, I need you to take a couple of calls from another department." I told him "That's fine."
From that moment forward, I took dozens of calls from that department non-stop for the remaining five hours of my shift. I guess my company's definition of "a couple" differs from mine.
So tomorrow morning, I'm calling that manager and telling him I'm going to be a couple of minutes late for work.
