You're a Bunch of Factors

[b]spectators and players out of the game should not be allowed to sit at the table of a game still in progress.
especilly the final table where any one not in the game should be at least1/2a meter away from players and should be discouraged from conversing with players
alocation of seating should be such that lovers,married couples and mates don't sit with each other as in some cases it encorages two playing the one hand
some laws are in place to cover the above ,but most times there are not forced.

No stopping loved ones from sitting with each other.
But if you do have issues then discuss it with your TD, as to that I don't see much point to this post unless you are wishing clarification on a rule or stating assumptions or on your opinions?
