Soggy afternoon tea

Our second day in London today. We had a very lazy morning watching tv. We then headed over to Trafalgar square where we had pre-booked afternoon tea. The moment we crossed the road the heavens opened and we got soaked. It's not til you need shelter in Trafalgar square that you realize how open it is.
We had a lovely afternoon tea, same we had to sit there in our soaking wet clothes :-(
