Flying from SFO to ORD a few weeks ago, 789 was swapped from a new to an old config. Traveling alone and was moved four times accommodate couples traveling together. I really felt bad for the flight crew as they were so confused when they came to take orders. Normally I'm happy to swap once or twice assuming the seat was the same, but it was getting a little out of control. Got to the point where couples were arguing with each other about which set of two each should take.
