All I can say is thank you for being so helpful. I've been in similar situations such as a wheelchair arriving at the end, or a single mother with two small children, for example. There are plenty of people who despite being asked nicely, refuse to move (regardless of the reasons). You could have done the same, but because you're nice, you helped out everyone: the wheelchair pax, the ramp agent, the crew, the other pax by not causing further delay. Many people buy Speedy boarding, not to get an emergency row seat (they don't want the responsibility and size difference is miniscule), but because they want to skip the queues at check in and be called first at the gate. (IMHO a refund is unlikely). The operating crew should have asked you more nicely, as it is a courtesy, but again, thanks sincerely for helping out!
