When I play games (causally) that involve face-up cards across a table (hold 'em, blackjack, etc), I usually have to either ask that the cards be placed closer to the center (toward me), particualrly at larger tables, in order to see them. I can imagine that this would be an imposition, and perhaps even barred, in a casino setting. And I imagine that even if I could ask that cards be announced when dealt (I don't know if that's possible), that I wouldn't be able to take notes to record them so I'd have to memorize the table every hand.
Are those impressions correct? If so, what affordances are available to visually-impaired players? Or is this just one of those cases of "sorry, don't try to do that"?
(I ask this question out of curiosity, not out of an impending desire to jump into casinos, for which I'm not good enough.)
