Delta Airlines

At the airport for a 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 "Thank you for participating in Delta's physical fitness program."
