What I am going to do is sit at a blackjack table and see if while sitting in the chair and turning in the seat (not turning the chair) I have a view of the cards or where the cards would be on any other blackjack table.
Frankly, Unless I am a very tall person (I'm really 5' 10") I doubt my eye level is going to allow me to see the exposed cards on any other table. A photo taken at my eye level will show me and the others if it is possible.
Why are you not agreeing to this simple test?
Name the casino. I'm here in Vegas ready to go.
