I had an event at work this week which I had organised and had been worrying about. It went reasonably well - all of the speakers turned up and on the day the delegates seemed pretty happy. But yesterday was spent going through their feedback which is so disheartening. Overall the response was still good, but people's little moans really get to me.
The award for the best complaint goes to this gem, in answer to a question about the event's catering:
"The biscuits were too far away from the cheese."
