Does Anyone See the Captain?

This was not a rhetorical question. A recent flight was delayed because we had only a first officer, but no pilot or flight attendant. The gate agent helpfully asked those of us waiting in the gate area whether we had seen either of these individuals, to much amusement (hearty laughter preceded the anxiety). In fairness, her aggravation was equal to ours. Fortunately, our tardy crew did appear, but not before clocking a 20-minute delay.
