I recently had a licence issued. Since I live near Gatwick, I decided rather than have my logbooks sent back to me in the post, I would collect them personally when the licence was ready. I watched them write this in big letters across the top of my application.
Two weeks later, the whole lot arrived in the post! Good, it didn't get lost and it saved me a journey, but had it got lost, I would have been very peeved...
