I just got a chance to hang up on this lady.
And I took it. Gleefully. And I only feel a little guilty.
(She called to tell me that hey! She does have a 3-day spot opening up soon after all, and there are only 3 people on the list ahead of me! Aren't I excited? It was when she sheepishly said, "Oh, you must kind of think I'm out to lunch," that I decided I could be straightforward with her, and when she AGAIN denied hanging up on me ("I didn't hang up on you, the phone just did whatever it did,") that I decided immaturity was the better response.)
(The last thing I heard her say before I hung up was "So, you're telling me that after we've done all this work, you don't want the spot? FINE!")
