@johncarlosbaez @ojs yes, I agree. In the painting the mirror seems to be showing a different scene than the non-mirrored part. It is only from the explanation of what we are seeing that the interpretation of the two customers start to appear.

@ojs @johncarlosbaez I would in fact say she doesn’t seem to be serving the man. A more plausible version is that she served the man already and she is looking at the next customer, the viewer/painter/photographer.
