Cafe chat - capturing the mood

This is not a great image in terms of quality, but there is a lot going on within the frame, which is why I have selected it.  Taken today on my mid day walk I came across activity outside the village cafe - two involved in deep conversation and enjoying a coffee, another person engrossed in her smartphone and with her back to the others and finally someone emerging from the premises.

It was important that the subjects did not notice me, so the shot was taken very quickly, depending on zone focusing entirely.  Contrary to my usual dislike of cropping, this image has been cropped.
