Update - I returned to this payphone and after waiting ten minutes I saw this these payphones being used by four people! Who said payphones aren't used any more. I will come back to see to monitor their use again sometime. There's a nice little coffee shop for me to chill out in while payphone user spotting. Anyways, below are some pictures of the people using the payphones in the time I was there. I tried my best not to saw their faces. But some of the passers by are quite funny.
Revisited this payphone today (27.11.15). Happy to report all is well. Rings nice'n loud and is exactly as it's always been. Can also add the remaining payphone numbers too: +442078372225, +442078332936 and +442072784547 along with some pictures from today.
