At the airport for a business trip, I settled
down to wait for the boarding announcement
at Gate 35. Then I heard the voice on the
public address system saying, "We
apologize for the inconvenience, but Delta
Flight 570 will board from Gate 41."

So my family picked up our luggage and
carried it over to Gate 41. Not ten minutes
later the public address voice told us that
Flight 570 would in fact be boarding from
Gate 35.

So, again, we gathered our carry-on
luggage and returned to the original gate.
Just as we were settling down, the public
address voice spoke again: "Thank you
for participating in Delta's physical fitness
program.
