It's street photography. It captures what happens on the streets or life on the streets. Not quite documentary though. For a harder hitting shot, maybe could have waited a while until the alcohol really kicked in I guess. . . But still wouldn't be trying to convey anything in the sense that you have outlined, but more a portrayal of some of the less mundane things that happen on the streets. Harder to find and catch than a lot of the usual street stuff. Especially when going in close, which this was and wasn't.
