We had to be at the airport (London, Gatwick) for 7.10am so we were up bright and early. We left a little late (in my house, the more people involved the longer it takes to get in the car and the more likely we are to forget something and have to go back) but the motorway was clear and we were in plenty of time.
So, I hand Gill the valet parking details and say "phone this number 10 minutes before we arrive at the terminal". Being organised, this is the service where you give the car to someone, saving you all of the hassle of finding the car park, getting on a bus and driving around the airport. I'd organised this to save hassle and have a nice relaxing airport experience (unlike last year's mad cramming onto buses).
Unfortunately, Gill could not get connected. She tried and tried, but no luck. Eventually, we were at the terminal. I 'phoned and they said they'd be 10 minutes. Traffic was heavy and it was nearer 20 minutes by which time I was having kittens and wondering if I should dump the car in the long term car park.
It wasn't until 3 days later that Gill told me - she'd been dialling the wrong number.
