Long story:
I was taking ds to an annual event we'd been to before, we'd never got advance tickets because it was never that busy. About 3-4 miles away we hit a queue which was moving very slowly. I assumed we were coming up to roadworks or something.
There was a cyclist on the side of the road stopped to have a drink and I was chatting to him as we stayed stationary and I asked him how long the queue was. He told me it was for the event so all the way. But he then told me that if I took the next right it would go down a very windy single track road and skip the queue.
I reckoned we wouldn't get in otherwise, so risked it (don't like that sort of road when I don't know it) and came out less than half a mile from the event.
We arrived at the field to park in. Normally at that time you walk straight to one of the ticket booths (there's about 3 or 4), pay and get in. This time every booth had a queue that had 100s of people in, right the way from one side of the field to the end and back.
I said to ds that we weren't going to get in, so why didn't we sit down by the fence, have our pack lunch, we could hear a little from there, and then we'd go home.
And he agreed.
So we sat down by the fence and I got lunch out and this official came up to me followed by about a dozen people. He asked, "are you paying by card?" I said, "if I can get in, yes."
He told me to follow him. So rather confused we did.
As we went, the people with him told me that they'd got to the front of their queue and the card machine had stopped working. He took us to the front of another queue and asked the chap behind the counter to put us through.
Well, the people at the front of the queue went mad. Yelling, and shouting that they'd been there first. Our official explained to them, but they weren't having any of it, and they were squaring up to him-looked like it could get nasty.
Our official was obviously irritated, but then said. "For goodness, sake, my group, follow me..."
He took us to the entrance and told them to just let us in for free.
As we walked through the entrance there was an announcement that the event was now full and no one else would be let in.
My day of good luck!
