The ethics of seeing a player's cards

[Lucere]

So the other day I was playing 1/2 NL with this fat woman to my immediate right who just moved over from a 3/6 limit table. I don't know if it was because she was fat, or that she simply didn't care, but every time she got a new hand, she looked at it way out in front of her with the cards up for anyone to see. I could easily see them every hand without even having to move my head. I'm sure the guy on her right could also. Maybe she couldn't get both arms in there closely so she could cup her hands to cover her cards? This isn't the first time this has happened to me either. If someone is not even trying to conceal their cards, is it wrong to look knowing you'll get information?
