Looking at other's card. It's ok?

[baggins]

i've had it happen before. usually tell them once. then i have no problem taking advantage if i don't have to contort myself to actually see the cards. i won't go out of my way, but i won't NOT use the info if i have it.

as far as it not being fair because other people don't have the same advantage - you could say the same thing about isolating a maniac on your left. not everybody has the same positional advantage, but it doesn't mean it's wrong for you to use it.
