I really like this, particularly the expression on the butcher's face, to me it looks like he's thinking "blinking customers" and sharing that thought with you ( or whatever the Italian for "blinking" is..mamma mia ?)
I'm not usually a fan of candid people shots, this one I like as the subject is clearly aware he's being photographed.
My only comment, as a viewer, is that I find the overhead light distracting, it draws the eye to it, and wonder how the shot would look with it cropped out.
