This is all so incredibly outing but I am curious to know what others think so I will keep it a little vague but I can't imagine too many kids did this (or maybe they did!).
When I was 14 I lived with my mum and step dad near Heathrow. I HATED it, but that is all another story. Most of my family are from another European country. After a big fight I waited for them to go to sleep. Packed up a school bag of clothes. All the money I had access to and climbed out my window.
I walked to Heathrow, a few miles along a dual carriage way, under the tunnel and into the airport. So dangerous it makes me cringe, I had a man stop and offer me a lift.
I then went to the desk and asked for a 1 way ticket on the next flight. This was approx 3am. I was told the price, counted out my money, including a huge pile of change. I also had to leave the desk and go change some Euro's.
They sold me a ticket and I flew home. I had just turned 14 a week before, now that I am older I really don't think they should have sold me a ticket. This was 2006 by the way.
YABU - they should have sold the ticket
YANBU - they should not have sold the ticket
I get that the person at the desk may not have known what to do, but I wasn't questioned at all.
