I'll start.
I was flying BA JFK to LHR. I wanted to get the front row seats so i told them I sprained my ankle, and they gave me the front row.
When I was checking in they asked me if I needed a wheel chair, I told them I don't need one now but when I land I will take one. I totally forgot about it.
When I got off the plane there was a wheel chair waiting for me. I went in.
There was a huge customs line, they took me to the side and the agent just stamped my passport and let me right through.
After the attendant brought me to baggage claim, i picked up my suitcase said thank you, gave him a tip and walked away.
