Yes, I do thank you. And I know there are other stations, I've used them. And as I said in my post, my son was in the same situation after the 2017 terrorist attack in that area, he managed to find another way home. It took longer but he got there, and he didn't whine about it.
You clearly don't understand how the trains in London work then. This isn't a case of walking 5 minutes to the next underground station, LB is a terminal station. I get my train there, and the next stop is over 40 miles away, that's not something you can walk!
