The OP may have a different answer but concerning 1 - I watch tables quite a lot and have never had anyone ask me not to, nor have I noticed any funny looks from players. Just be courteous and don't hover too close and I think you should be ok.

I see anecdotal reports every once in a while about the facial recongition used by casinos, how good is it really?
I'm also interested in what it is used for other than the obvious - tracking known card counters is an obvious one but in what ways is it used that aren't so easily guessed.

Last time I was in Vegas I stood by the craps table thinking I could understand what is going on, an later I went back to blackjack.
I think next time I'll try to read a primer on craps before I go.....

My mother just found it funny to let me and my brother wear purple and pink :)

No they don't, they are all one color!!!!
I've been convinced of this for too long, don't ruin it for me :)
