When girls go shopping, not all men feel like joining them going in and out the stores. I don't think this guy is happy neither. He prefered a job as dogsitter, while his girlfriend was trying to get rid of some money.
To the left of the picture, you see a name cut in the bench "flore", as if the girlfriends name is "flore" and she is missing at his side.
The dog is still looking for her, while the boyfriend has given up, thinking what she could have bought.

Apart from the b&w, contrast enhancement, there is only some vignetting applied.
