Maybe this is a bit of a culture clash (I'm Swedish) but my initial reaction is: This has an almost sexist undertone to it (what kind of a man would treat a woman like that - she's absolutely helpless and couldn't even comprehend why I was suddenly gone) and it feels rather unprofessional.
The only people who where treated really badly here as I see it where the (hundreds?) of people who payed for their passes, stood in line to collect them and expected to hear a talk that never came.
Sure you can be annoyed somebody treated your wife poorly, but the appropriate response is an email to the organizers after the event or similar. That's my 5 cents at least.
