Thank you, Mike, for your reply.
The thing that really upset me was seeing very elderly people (I'm no spring chicken, but...) 'discharged', like cattle, at Gatwick at 00:30-ish, rather than mid-afternoon, and just told to get on with it. Many of them couldn't walk easily. No trains running at that time of night, no assistance from Olympic staff, what do you do? We're lucky enough to live relatively close to Gatwick, although it did incur an extra day's parking charge.
I wonder what happened to the rest? Olympic had had their money so I don't suppose that they didn't give a you know what.
I travel a lot with work, and when I had a dicky foot at Indianapolis, and then Chicago, airports, the security people couldn't have been kinder. I was trying to use my bag as a crutch - didn't want to make a fuss - but they wouldn't have any of it. They put me in an electric car and sped me through security, and ensured that BA did the same at Heathrow. What a difference from Olympic.
I know that life isn't fair, but deliberate, pre-meditated, unfairness makes my blood boil.
