Picture Problem

There are four pictures of Jake leaving Parma restaurant late last night but they create more questions that answers like:

Why only 4 pictures? That's not even a second of photography - they shoot 10-12 frames a second.

Was there someone that they didn't want to have pictures of taken with Jake?

Who would eat alone so late at night?

It looks like he is coming from somewhere up the street and walking past the door. Why not use the door to the restaurant?  Why did he have to use another exit if he was all alone?
