One Friday, at a previous job, someone I'd never seen sat down by the receptionist's desk and started chatting up a storm. After she left, a co-worker asked the receptionist, "I take it she's a friend of yours?" "No," the receptionist replied. "She's a salesperson. I asked her to come back Monday."
I always wondered if the salesperson came back. Luckily for the receptionist, our company moved across town that weekend.
